AITA for telling my ex’s new husband he’s a selfish fool for marrying a lazy part time mom and thinking he could use my kids to help with his own?

Feeling the weight of responsibility can be normal for older siblings, but when it becomes an expectation, it crosses a line. In this case, a devoted father discovered that his ex‑wife’s new husband was asking his 11‑ and 13‑year‑olds to babysit and care for his younger children—even texting them directly for help during their custodial time with their dad. The father’s protective instinct kicked in, leading him to pick up the phone and firmly tell the stepfather to back off.

This confrontation culminated in a blunt rebuke: the stepfather was a “selfish fool” for marrying a part‑time parent and presuming the father’s kids existed to raise someone else’s. Such blatant parentification doesn’t just infringe on childhood—it can leave lasting emotional scars.

‘AITA for telling my ex’s new husband he’s a selfish fool for marrying a lazy part time mom and thinking he could use my kids to help with his own?’

I (34m) have primary custody of my two children (11 and 13). Their mom and I were high school sweethearts who had kids too young and while I stepped up, she didn't. With our first she made some attempts, kinda, but once she got pregnant for the second time she used pregnancy as an excuse to do nothing.

She didn't have a high risk pregnancy, wasn't in pain and never expressed actual concerns for her or the baby's health and safety. But she'd say pregnant women shouldn't be standing for too long, shouldn't be near heat (to cook), shouldn't be bending over to tidy up, shouldn't be driving or pushing heavy shopping carts around, shouldn't be pushing dust around, etc.

My ex's parents watched our oldest while I worked back then and she'd text me while at work to bring her snacks or magazines, etc. And she expected me to tell work to f**k off and get her that stuff there and then.

I tried to stick it out and at the time I expressed concerns for maybe a pregnancy depression or some form of early PPD but scoffed at that and no medical provider saw concerns about it. When our second child was born she continued like she was still pregnant.

Even 2 and 3 months post partum she said she shouldn't be holding things, lifting things, driving, etc. I finally had enough and we broke up when our youngest was 4.5 months old after I did all I could to try and find an excuse. I just had to accept she was lazy and didn't care enough to do anything.

She wasn't working either so I was doing it all and taking care of her. I filed for custody of our kids and won very quickly because she showed up in court unprepared and only fought against it half heartedly without retaining a lawyer for the custody case.

She couldn't answer a single question about either of our children. Because she did request 50-50 they did a fitness check on her and she failed. She didn't fail enough to get no parenting time. But she was deemed unfit for 50-50 custody and so she gets every other weekend.

And yes, that every other weekend is something the kids and I hate. But I have not been able to convince her to give up her weekends or convince a court to not force it. So she sees our kids that much and they basically take care of themselves over there.

Which is documented and I have shown proof to the courts but it was not enough for removing her visitation rights. My kids need to be 16 before their voice holds any weight in the judge's decision. Any younger and the judge will not listen to what the kids want.

Anyway, my ex has been remarried for I'm not sure how long. But within the last year. Her husband has two (or maybe three because there could be twins in there) very young children (younger than 4) and he expected my kids to be around more and to help.

I'm sure he expected more from my ex as well. But the kids said from the time they met him, which is when he moved in, he's been asking for them to babysit and bond and help with childcare stuff. They refused to help and they ignore him and ignore the very young children.

But he even started asking for their help when they're with me. When my kids showed me messages he had sent I called him from my phone and I told him to leave my kids alone. He told me the kids have younger siblings and I stopped him and said neither my ex or myself had more kids so they don't have younger siblings.

They have each other. He told me he married their mom which makes his kids their siblings. He said older kids are meant to help with younger ones and he isn't supposed to be doing all of this alone.

This is when I told him that he was a selfish fool and pointed out he married my ex, a lazy part time parent who doesn't even deserve the title of parent because of how little she does, and spectacularly selfish for thinking my children existed to help him raise his kids. I said you do not put that responsibility on kids.

On anyone's kids. But especially someone else's because you do not have the right to have pre-conceived ideas of what someone else's children owe you and yours. He didn't like that I insulted him and interfered in his marriage.

I told him he interfered in MY children and as their dad and their sole parenting parent I have every right to put my foot down about what he expects out of my kids. Since then he has tried to call me multiple times and he texted me repeatedly. And I don't block him because I would much rather he contact me than my kids.. But AITA for how I spoke to him?

When children are thrust into adult roles—such as caring for younger siblings—they experience parentification, a form of role reversal that deviates sharply from healthy developmental norms . Instrumental parentification involves practical tasks like cooking or supervising young children, while emotional parentification turns a child into a confidant or mediator for adult issues .

Long‑term studies show that parentified children face higher rates of anxiety, depression, and low self‑esteem, as they miss out on the support and free play essential to childhood . These young caregivers often carry excessive responsibility into adulthood, struggling with boundaries and feeling perpetually “on guard” to meet others’ needs .

Blended families can amplify these dynamics when stepparents assume older or step‑children will serve as “instant helpers.” Pioneering family therapist Ivan Boszormenyi‑Nagy warned that chronic role reversals erode trust and sow deep resentment within blended households . Expecting children—especially those from another union—to fill adult gaps breeds conflict rather than cohesion.

Healing from pathological parentification begins with clear boundaries and professional support. Trauma‑informed therapies, like Cognitive Behavioral Therapy, help affected youth reclaim age‑appropriate roles and rebuild self‑worth . Meanwhile, family systems therapy can guide caregivers in maintaining their proper roles, preventing future parent–child role confusion .

Here’s what the community had to contribute:

Redditors largely sided with the father, recognizing that his stepchildren should not be conscripted into unpaid caregiving. Many praised him for protecting his kids’ right to a normal childhood, highlighting that parentification is a serious issue rather than mere household help.

While some warned against escalating conflict with his ex and her husband, the consensus was clear: setting firm boundaries is essential when children are being exploited for adult chores.

Alicat52 − NTA. Your kids are not required to babysit his kids. He had no right to text them without going through you first. And I doubt he would even pay them for their help. Your ex is lazy, and it seems he is, too. I foresee a divorce in their near future.

EarlyElderberry7215 − NTA, I see is a parent standing upfor his children and protecting them. Also see an other parent not being present and neglecting her job to protect her children from this.

Material-Ad5623 − Oh my. NTA at all. Please keep all these records. I saw a comment that you were harsh, I disagree. This man is taking advantage of children, your children and you did exactly what a parent does by sticking up for them. They will remember this. I hope this will help you with custody because they are not safe over there.

Buttered_Crumpet09 − NTA. I think your ex found a perfect match in her new husband. I suspect he thought that when they married, he'd be able to d**p his parental responsibilities on her and/or your kids. I am awfully curious, though. Did he know about the custody situation before they got married?

If he did, he's insane and stupid. Why would a woman who doesn't parent her own kids and only sees them every other weekend step up to help raise his kids? And how on earth would he think that your kids would bond with him and his kids in that time? He's acting like marrying their mum instantly created a magical bond.

And if he didn't know, the question is how? Did they not live together or know each other for long before getting married? It's so bloody weird. Either way, your kids are not bonus parents and free babysitters for your ex's stepkids.

The fact that l**atic new husband thinks you'd actually give up your parenting time so you could pack your kids off and send them to do the child-rearing he and your ex clearly don't want to is just mind-blowing. You might have been blunt but no matter what the situation, he's an overstepping i**ot.

mcmurrml − Go dad!!! That's fantastic! I got a big smile on my face because of what you said to him. Your kids are not required to lift a finger in that regard. He wants caretakers. Glad the kids did not play into that.

They have a way to reach you? I would tell this guy every last thing she didn't do. Glad you set him straight and keep documents and glad you have a good relationship and keep the lines open with your kids.

Cursd818 − NTA Warn him that if he leaves his children with your kids, you will tell them to call the police for child abandonment. He has no right to try and parentify your kids because he and his wife are too lazy to raise them. Keep rproectjng your kids and see if you can go back to court with how much he's harassing you and trying to enslave your kids.

Maverick_j2k − NTA. Don't answer him back or delete/block him. SAVE THE MESSAGES! Go to court and show them what's happening and why you need more custody or at least supervised. Good luck.

k1rschkatze − First off, NTA. There have been plenty of comments detailing why. . Second, I have no idea what your jurisdiction is like, but I wonder… - what happens, if your kids just refuse to go to their mom? Would she have any way to enforce this, if so - how, and would she bother? What would be the worst repercussions to realistically happen to you and the kids?

if refusing to visit doesn‘t go anywhere, (and I may wander into r/UnethicalLifeProTips land here, but… sometimes you gotta fight fire with fire) what about teaching your kids about malicious compliance, weaponized incompetence and the like, to make the visits as miserable for the adults as they are for your kids?

This may be as simple as spilling a glass of milk on their couch (or two), throwing a tantrum, and pulling some harmless „kids being kids“ stunts (that may already be that puberty thing I hear people complaining about all the time)

or would it be viable to just go after the new husband for the parentification harrassment and whatever true stuff you can come up with to achieve that he is not allowed to be there when your kids are?

Please be up front with your kids about that very thin line between standing up for yourself and becoming an actual a**hole, but from what I read and how you are reflecting on yourself

You did and are doing a great job raising them to become good people, and a part of that would be teaching them how to stop people from taking advantage of them - where neccessary and just as much as needed to make it stop. 

You don‘t want to drag this out until 13 reaches 16, and 11 is on their own, as THAT situation would put some serious strain on the relationship your kids have with each other, no matter how that plays out. . Also, you go, dad!

Cybermagetx − Nta. He married her for child care and a bang maid. When a women doesn't have primary custody of her kids it should tell you thats not gon a be a thing.

Future-Nebula74656 − NTA. You are a parent protecting your children and that's how the sweets to me Now it's a little bit odd I guess it depends on what area you're at .. I know someone that had primary custody of their children from the age of 9 & 12 because their mother was like you said... The 12-year-old spoke up and was able to make the decision also for the 9 year old..

and this was before cell phones.. Now with cell phones your kids could be recording stuff over there depending on if you're state is a one party consent or not And you would think if her partner is now harassing your kids and harassing you that lawyer would be able to get you full custody

Children deserve the freedom to be children, not unpaid babysitters. The father’s decisive reaction underscores the importance of defending healthy boundaries in blended families.
