AITAH for letting my boyfriend date his ex?
We all know that sinking feeling when you realize the person you love is slowly rewriting the rules of your relationship to suit everyone but you. For one 31-year-old man, a stable eight-month romance turned into a masterclass in emotional neglect when his 24-year-old boyfriend insisted on “opening up” their dynamic. Despite a deep-seated lack of interest in polyamory, he agreed to “try it” as a desperate attempt to save the connection, only to find himself sidelined on the very days they had specifically reserved for their “us time.” Working grueling overnight shifts and staying awake just to catch a few hours of quality time, the original poster soon realized that his partner’s idea of an “open” relationship was one where his partner’s heart—and his schedule—were closed to the man standing right in front of him.
The betrayal didn’t stop at simple scheduling conflicts or missed texts. From a forgotten birthday that was only “saved” by a roommate’s intervention to a Valentine’s Day where thoughtful love letters were met with a four-hour delay, the boyfriend began prioritizing expensive dates and weekend getaways with exes over his partner’s basic emotional needs. While the original poster showered his partner with gift cards and words of affirmation, he was met with store-bought apologies and a shocking “phone call” where a third party was invited to interrogate him about his boundaries. It wasn’t just about dating other people; it was about the complete erasure of the original poster’s dignity. Curious how it all unfolded? The full story is right below.
AITAH for letting my boyfriend date his ex?
So me (31M) and my boyfriend (24M) have been together for about 8 months. He had told me that he wants to be in a polyamorous relationship. I let them know that I do not have any interest in being poly. He kept bringing up the topic and wanting to open up the relationship. Finally about three months ago, I said I would try it. I said as long as there was communication and he let me know ahead of time that we can try it. My only thing was that I had Mondays and Tuesdays off, so those are our days.
Fast forward a couple of weeks and I find out he has a couple of hangouts planned. And I asked about details of the hangout, and it was this guy (we will call Alec) and he was going to take him out to breakfast and pay for everything. I told him that that was a date. My boyfriend told me no it wasn’t and that it was just friends. He said that this was an old friend and they were gonna catch up. Now here comes the kicker, this was planned on a Monday. I’m off Monday. I let him know this and he said he forgot and he thought I was gonna be sleeping. (background.: I work overnights and I get off at 7:30 AM on Monday. I stay up all day Monday and go to bed at a normal time Monday night. And this is every Monday.) I let it go and told him to enjoy his day.
A couple weeks later was my birthday. I was super excited because one of my love languages is gifts. I love giving gifts and I love receiving gifts and my boyfriend knows this. I know this kind of sounds shallow, but even if it’s homemade and doesn’t cost money, I will love it regardless. My birthday fell on a Monday. I get off work and find out he has plans to meet up with another guy. I thought maybe this was a cover-up so he can get a gift. I was wrong. He admitted to me later that he forgot until my roommate texted him letting him know that it was my birthday and if I was gonna do something. Mind you this was already about 1 PM that he realized it was my birthday. He ran out and got a store-bought cake and some flowers. In my mind, this was strike two, but I let it slide. I was honestly very hurt. We had a big argument, and I thought we had come to another understanding that Mondays and Tuesdays are for us.
A couple weeks after that was Valentine’s Day, on a Saturday. I was really excited and I planned out a whole thing. I had a letter for each hour planned where he would open it and find a love message from me. There were some that had gift cards attached to them (DoorDash, Steam, PlayStation store,etc). His love language is words of affirmation. Some of the love letters were words of affirmation. I was super excited. The day before he lets me know he has a hang out with another guy planned. I was really hurt to be honest. I let him know this and he said that he would be back by the time I was up sleeping. (background: on my work week I get home around 8 AM and go to bed until 12:30 PM. And then I take another nap around 6 PM to 10 PM.) I said OK and waited for him. He didn’t end up coming home until 4 PM. I decided to sacrifice my sleep and stay up to have a Valentine’s Day with my boyfriend.
In the next month, I found out he had reached out to two more of his exes. He wanted to go on a weekend trip with one of them and the other one he was talking to over discord. Mind you the one he was talking to you over Discord broke his heart, and he’s still in love with him. The one over Discord does not have feelings for him whatsoever. The one that he wanted to go on a weekend trip with we will call Eric. He stated that Eric was going to order an Uber for him to his house and he’ll Uber him back at the end of the weekend trip. Mind you the Uber is about $110 one way. Eric was also going to pay for all his food and of course weed for my boyfriend. I felt super uncomfortable with this. I had asked to meet with Eric just to feel him out. We had another argument of where I let him know. I wasn’t comfortable with poly yet. He agreed to set up a dinner so we can meet.
My boyfriend asked me to drive him to Eric‘s house to see if that would calm me down. I said yes that would most likely calm me down and we can have that dinner with Eric. Pass forward to the day of and we get in the car to drive to Eric’s house and he drops on me that we will just do a call and not a dinner. And so we do a phone call and Eric gang up on me and starts asking me questions of why I need to meet his dates. I let him know that I wasn’t comfortable and it would make me feel more comfortable in theory. Eric stated that he has a husband and that I should not put myself through meeting these guys. This did not sit well with me and I got super quiet on the phone. Call where my boyfriend asked me if I was gonna answer. I felt very good on and I said no. I dropped him off to his weekend and left. Eric did pay for gas, which was nice. In the next month, he knew planned about two more dates with Alec and they were all on Monday. He used that same excuse of forgetting.
A couple weeks ago he came back from his date and he was wearing all new clothes and jewelry and showing off of what his date got him. I felt very uncomfortable and I told him I am not comfortable with Polly anymore. I honestly tried and it is not for me. My boyfriend has stated that I am overreacting and I am being unfair. AITAH for this?
Expert Opinion
The situation described here is a textbook illustration of “poly-under-duress” (PUD). This occurs when one partner in a monogamous relationship pressures the other into opening the relationship through persistent requests or ultimatums, often leading the reluctant partner to agree simply to avoid a breakup. In the world of ethical non-monogamy, the “ethical” component hinges entirely on enthusiastic consent and the prioritization of the primary partner’s security. Here, the boyfriend isn’t practicing polyamory; he is practicing a form of sanctioned neglect.
According to Kathy Labriola, Counselor and Nurse, one of the most destructive mistakes a couple can make when opening up is using it as a way to “fix” a fundamental incompatibility. The boyfriend’s repeated “forgetting” of the original poster’s schedule and birthday is not an accident—it is a manifestation of New Relationship Energy (NRE) being used as a shield to ignore existing obligations. In a healthy “hinge” dynamic (the person dating multiple people), the hinge is responsible for protecting the emotional well-being of all partners. By allowing an ex-boyfriend to “gang up” on the original poster during a phone call, the boyfriend effectively abandoned his duty to provide emotional safety.
Furthermore, the research of The Gottman Institute emphasizes the “5:1 ratio,” suggesting that for every negative interaction, there must be five positive ones for a relationship to survive. In this narrative, the ratio is inverted. The OP is making massive sacrifices—including his sleep, his birthday, and his financial boundaries—while the boyfriend is returning from dates wearing jewelry from other men. This creates an attachment injury that is nearly impossible to heal without a total withdrawal from the polyamorous structure.
The boyfriend’s claim that the OP is “overreacting” is a classic example of gaslighting. It is a tactic used to make the victim question their own reality so the perpetrator can continue their behavior without consequence. For the OP, the path forward requires radical self-advocacy. Polyamory requires more work, more communication, and more consideration than monogamy, not less. If a partner cannot remember a birthday, they are certainly not equipped to manage the complexities of multiple romantic lives. Do you think a relationship can ever recover once “poly-under-duress” has been introduced?
Conclusion
It is heartbreakingly clear that while the original poster was busy writing love letters and sacrificing his precious sleep, his boyfriend was busy shopping for a new life. Relationships are built on a foundation of mutual respect and shared priorities, but in this case, the foundation was traded for weekend trips and store-bought cakes. When someone shows you who they are—especially someone who “forgets” your birthday while planning a date with an ex—you have to believe them the first time.
The original poster tried to be the “cool, flexible” partner, but the price of that flexibility was his own mental health. There is no such thing as being “unfair” when you are simply reclaiming your right to be treated with basic decency. Sometimes, the most loving thing you can do is realize that you are not a “safety net” or a “home base” for someone who only comes back to you when their other dates are over. You deserve to be the person someone stays awake for, not the person they “forget” on a Monday morning.
Community Verdict
The community response was a unanimous chorus of support for the original poster, delivering a resounding “Not The Ahole” verdict. Commenters were quick to label the boyfriend’s behavior as “cheating with reluctant permission” rather than actual polyamory. The consensus was sharp and direct: the OP isn’t just being treated poorly; he’s being used as a financial and emotional safety net while his younger partner “plays the field” without any regard for the rules they established.
