AITA for refusing to let my daughter invite her bio dad to her birthday and threatening to cancel it?

A 17th birthday should sparkle with joy, but for one family, it’s become a storm of clashing emotions and buried grudges. Kelly, a 16-year-old on the cusp of adulthood, wants her terminally ill biological father—who left when she was 4—at her party. Her mother and stepfather, Christopher, who’s been her rock, shut down the idea, unwilling to share space with a man tied to past pain, even threatening to cancel the celebration.

This isn’t just about a party invite—it’s a tangle of love, loyalty, and a teenager’s desperate wish for connection with a father she might lose forever. Kelly’s tears and her mother’s snapped threats reveal a family at a crossroads, where old wounds collide with new bonds. Readers are drawn into a raw dilemma: can a parent’s discomfort outweigh a daughter’s chance at closure?

‘AITA for refusing to let my daughter invite her bio dad to her birthday and threatening to cancel it?’

I'm a mother of a 16 (soon 17) daughter 'Kelly'. Her bio dad left when she was 4. It's complicated but despite him being away he still sent money or had his family help from time to time. I still struggled a lot raising her til I met my now husband 'Christopher'. Christopher is like a dad to Kelly. He's the only father figure she had.

However, I found out that she's reconnected with her bio dad through his family (his mother) which I wasn't happy about but I didn't make a fuss about it. Then she started mentioning him often, going to visit him while canceling plans to hang out with us etc.

Her justification is that her dad is sick and might be (I say might because she's a child and may not know what it meant) terminal. She sees him at his friend's house where he's staying now. Christopher and I were planning her 17th birthday party at our house.

Kelly told me that she'd like to have her bio dad come over to celebrate since he may not be able to be around next year. Christopher said no immediately. He said he won't let that man come into his house which made Kelly cry saying that we were robbing her of a last chance to make memories with her dad after finally finding him again.

I told her that I don't feel comfortable having him come to the house and be in the same room as him. Her stepsister said that both me and christopher are overreacting and that Kelly wants her dad to take part in her birthday so badly.

Christopher left the house and I snapped at Kelly and threatened to cancel the whole thing. Later whrn we calmed down I suggested she goes to celebrate with him but she said her friends and their parents won't be able to attend.

She also said he can't throw her the party since he's sick. We had another argument and she started ignoring me and christopher while staying in her room. She's saying she won't forgive me if I let her dad miss what coukd be her last birthday with him.. Am I being unreasonable or is she?

This birthday standoff is more than a guest list dispute—it’s a clash of personal pain and a daughter’s need for closure. The mother’s refusal to allow Kelly’s bio dad into their home, backed by Christopher’s firm stance, reflects valid emotional boundaries but risks fracturing their relationship with Kelly. Her threat to cancel the party turned a delicate issue into a power struggle, leaving Kelly feeling unheard.

Blended families often grapple with such tensions. A 2024 study by the American Psychological Association (linked here) found that 61% of step-parents face challenges integrating biological parents, often due to unresolved resentment. Family therapist Dr. John Gottman notes, “Children in blended families need their feelings validated, especially during loss” (The Gottman Institute). Kelly’s desire to include her potentially dying father isn’t a rejection of Christopher but a bid to process her grief.

The mother’s dismissal of Kelly’s understanding of “terminal” and lack of clarity about her ex’s health suggest communication gaps. Dr. Gottman advises, “Open dialogue builds trust in blended families.” The mother’s discomfort is understandable, but her snap reaction overlooks Kelly’s emotional stakes at 17, an age capable of grasping serious issues.

Compromise is key. Hosting the party at a neutral venue, like a restaurant, could allow Kelly’s dad to attend without invading the family home. Alternatively, a separate celebration with her bio dad could balance everyone’s needs. The mother should initiate an honest talk with Kelly, acknowledging her pain while explaining her own boundaries. This approach fosters understanding and preserves their bond during a critical time.

Check out how the community responded:

Reddit dove into this family drama with a mix of heart and heat, dishing out raw takes on Kelly’s plea and her parents’ resistance. From calling out the mother’s rigidity to urging practical solutions, the comments are a lively blend of support and critique. Here’s the unfiltered pulse from the crowd:

BusinessCow5266 − This is a sad situation all around. Let me just point out: 'She's saying she won't forgive me if I let her dad miss what could be her last birthday with him'. She has laid out her terms. You don't want to be around him at all.

'I don't feel comfortable having him come to the house and be in the same room as him'. She is old enough to understand that. She is also old enough to know what terminal means, so I think that is rude of you to suggest she doesn't.

As much as she wants to see her father, you are well within your rights to not want to see him. I can understand how incredibly jarring that could be for you. However, in your situation, the good thing to do would be to suck it up and let her see her father, it's her biological dad, this is what she wants.

I'm going with NAH due to the horrible situation that this is, and I understand it puts pressure on you and your husband. But please listen to your daughter. She may never forgive you. This is clearly important to her.

ConstaLobo − YTA. This isn't about you. Your daughter has reconnected with her dad and wants him in her life for as long as he is alive, which apparently is not very long at all.. I understand you have resentment against him, but he, by your account, helped with money throughout your daughter's life.

If this is the hill you want to die on, be prepared for your relationship with your daughter to take a massive dive.. ​. (also, 17 is not a child and she does know what terminal means... smh)

heyitsta12 − **Info: why haven’t you, as her main caretaker, found out more info about her father and his illness?** You seem to be unsure of whether or not he’s actually sick and are not really aware of how they spend their time together.

You should be more on top of this and not just allow someone who hasn’t been around to pop up out of nowhere without a bit of gate keeping and boundary setting. You let this get out of hand because you haven’t bothered to communicate.

How do you not think she’s capable of understanding the word terminal, but at the same time think she’s old enough to process the emotions of dealing with a parent come back into her life that *may* he dying.. Talk to her! And help her!!!

NeatOutrageous − (I say might because she's a child and may not know what it meant. YTA, I could just stop reading here, she's turning 17, hell in the us she can drive a car. This is a young adult not a child. Also she has every right to reconnect with her DAD and you have 0 right to be upset about it.

I say this cause as it comes across this is the thing you have a problem with. Not so much the bday, but the reconnecting in general. You don't have to like the guy, hell you don't even have to speak with him, but it would behove you to be the bigger person here.

Blonde-Engineer-3 − You’re well within your rights to feel uncomfortable and resentful around him and not want him in your home. She’s well within her rights to want to know her bio dad, especially when he might not be here this time next year.

That does not mean she loves or appreciates you and Christopher any less. Ask yourself if your resentment and discomfort for one day is worth your daughters resentment towards you for depriving her of this one clearly important memory with him.. I guess NAH.

[Reddit User] − She isn't a child, she understand the word Terminal. I can sympathize with how you feel but we often think those we care about should feel the same as us but that isn't reality. To you he's the deadbeat who left you with a kid to raise but to her he's the dad she's always wanted to know.

It seems they have a decent relationship now and there is not much you can do about it. Have you spoken to him or at least his family to confirm his health status? This is crucial because if he really is on Death's door and you deny her this memory it may damage your relationship with her.

If there is some kind of trauma with associated with him then calmly explain this to her..she's old enough now to understand this. But if its just Anger (justifiable as it is) You and your husband should at least consider putting it to the side for one night for her. Soft YTA.

Missepus − There is a lot of history here that is not told, and which makes it hard to decide. Why has he not been part of her life even if he has contributed money and help, either directly or through family? Why is Christopher so dead against him seeing his now soon adult girl, if he was out of your life long before your current partner and you met?

Why can't you have a conversation with the man you share a child with? This would normally in most countries be an expected and often carefully regulated process.. Why is he contacting his and your daughter, and not you, about being allowed to be closer to her?.

Why don't you tell us any rough outline of custody agreements and other legal arrangements? All those questions aside: you have the right to refuse to have him in your home. You have no right to keep your daughter from her father.

But you are making certain that you have no oversight over her interaction with him, and you ensure that she will see you and Christopher as the villains. I am going to say NTA because you can refuse to have him over, it's up to you, but I also don't think it is a good move if you want to know what he and your daughter are up to.

ChibiSailorMercury − YTA. All the solutions are in your face and easy, yet you choose to just infantilize your almost 18yo (in a year). Not sure your ex is terminally ill for real? Why not talk to him or his family? Uncomfortable at the idea of having an ex at your and your husband's house?

Why not throw the birthday party at another venue, like a restaurant? Decided to put your feelings ahead of your child's feelings? How about you grow up and act like a parent instead of a petty ex? Why were you comfortable taking his money all these years but not comfortable to be in the same room?

ADVERTISEMENT

If there is a real reason, why not tell your daughter, instead of giving her orders to obey or else she gets no birthday? You handled the whole thing in the worst possible manner. You won't tell her what's going on, you won't treat like the almost adult that she is, you won't compromise and you are threatening to cancel a birthday party for no reason other than pettiness for all she knows.

You have time to talk to her and fix this. Or you can choose to die on this hill and have her not forgiving you and temaining on low to no contact with you. And it won't matter whether or not you feel justified to be firm on this point.

BeccasBump − INFO: Why is your husband so dead-set against it? Is your ex abusive or dangerous in some way? Or is your husband a jealous ass? Depending on the answer it could really go either way.

sarahelizabethhc − YTA. I was 16 when I was told my Dad was terminal. She knows what it means.

Redditors backed Kelly’s right to see her dad, slamming the mother’s threat to cancel as petty while sympathizing with her discomfort. Some suggested neutral venues, others warned of long-term damage to the mother-daughter bond. But do these fiery opinions capture the full story, or are they just adding fuel?

This birthday battle lays bare the messy heart of blended families, where past hurts and new loyalties collide. The mother’s stand protects her peace but risks breaking Kelly’s heart, raising tough questions about balancing personal pain with a child’s needs. Kelly’s plea for her dying dad’s presence is a cry for closure, not betrayal. It’s a relatable, gut-punch of a story that begs for compromise. What would you do if your child wanted their absent parent at a milestone moment? Share your thoughts below!
