AITA for ending my engagement over him having a sleepover with his ex

She believed in their love, counting down the days until their wedding, only to be left alone in their apartment, heart pounding with worry as he vanished into the night at his ex’s house. The silence on his phone was deafening, each unanswered call a painful echo of betrayal. Her trust shattered not by infidelity, but by the cold reality of being second to his past, she chose to walk away rather than live in the shadow of uncertainty.

When he finally returned, his anger clashed with her heartbreak, dismissing her pain as mere overreaction. To him, it was exhaustion; to her, it was a breaking point. Their worlds collided in misunderstanding, revealing how fragile promises can be when trust is broken and love no longer feels safe.

AITA for ending my engagement over him having a sleepover with his ex

I25f was engaged to my fiancé27m. We were together 2 years, and engaged for 5 months. My ex fiancé has 2 children with his ex, and last week he took his kids out for the day. He ended up sleeping over there, where he didn’t answer his phone for the whole night after 9pm.

The next day he texted me and said he was so exhausted he fell asleep on their couch. I was at our apartment, waiting and worrying about him.

When my ex fiancé came home, I was packing and told him I was going to stay at my moms and we were done. He was obviously really upset, and my reasoning pissed him off. He said there was nothing unfaithful with what he was doing, and that he was there with his kids and was so exhausted and just watched tv then passed out.

He said I was completely over reacting, and I needed to take a breath and stop acting this way. I don’t think I’m overreacting, he went MIA for over 10 hours, and had me at home worrying.

Here’s how people reacted:

NTA at all!! And this is from someone who has kids with an ex that I get along with as friends to make coparenting easier and sleep over at his house sometimes with the kids if the kids are having a rough week and want to spend more time with their father (due to his work schedule and the hours he works he can not have them any nights except Saturday alone and sometimes mid week the kids need their dad)

The nights I stay at my ex’s I let my boyfriend know that I’m staying there I also msg or face time him to talk like I do when I’m at home and he knows I sleep in the room with my kids. I would never stay there without letting him know in advance and not contact or msg him the whole time I’m at my ex’s. And it’s even worse for you because you live with him and had no idea he wasn’t coming home he gave no communication or heads up at all and that shows an extreme lack of respect or care for you.

Anytime a bf/gf tells you that you are overreacting and to calm down and nothing happened and they were sleeping and nothing unfaithful happened, doesn’t care about you or your feelings. Doesn’t care about how it looks, doesn’t care to see if from your point of view, doesn’t care how bad it hurts you, doesn’t care that you were worried and doesn’t care that you left, doesn’t love you. They only care about justifying their actions and defending themselves. Going MIA for 10 hours means he doesn’t respect you or your relationship, and he deserves to lose you. He IMO is lying and hiding, and what he did constitutes cheating. He is now an untrustworthy man who you will never trust again. Definitely NTA, move out and move on because he can’t prove that he didn’t cheat.

Nta, they did something. I have been in your situation. He claimed that same thing. He could check in anywhere and anytime, but at his kids’ mother’s house his phone miraculously stopped working. I decided I refused to sign up for a life like that. We all know if you disappeared at your ex’s house he would go ballistic. I realized that I needed to stop dating dad’s because I would never trust him especially when he disappeared while playing family with his ex and his kids. Do not give him any more of your precious 20s. You can move on and hopefully he learns from his mistakes and makes better choices. So he doesn’t ruin his next relationship.

I think any rational person would be extremely worried if you were expecting your SO to get home and they don’t call until the next morning. And the story includes sleeping at your ex’s house.

He is probably telling the truth, but the utter lack of communication is really upsetting. I would be pissed and would probably pull the plug too. If for no other reason than they didn’t have enough thought about me to send a text.

NTA- He is a dad doing daddy things with his baby mama. I mean it’s great they get along as parents so he can feel comfortable in her house with their kids. A true partner would have called you at a minimum to say I’m tired and sleeping over so you can tell him how bad of an idea that is. He didn’t want the fight. That man is not ready to let go of his ex.

If it feels like a lie, it’s either a lie or it’s beyond inconsiderate. NTA.

I was once out of town for work and my (now ex) wife “forgot her phone charger” while “staying at her friends house” for three whole days. While she somehow still managed to log in to Facebook, but did not even try to message me there.

NTA. Everyone needs to stop. OP already feels like shit you don’t need to add to it. There’s a great chance he fell asleep on the couch as he said he did.

IT DOES NOT MATTER THOUGH.

Because this is a hard line for you. You are allowed to have hard lines. Best of luck through your healing journey.

So he was ok enough to sit and watch “tv” before passing out. He could have at least used that tv time to call you either to inform you what was going on or to even get you if he was in no shape to drive. NTA it’s nice seeing a woman who knows her worth and actually leaves when she sees a red flag.

Lol I have my kids dad come and go to pick him up, I don’t see him sitting and watching tv, know why? Because I don’t fkn want him to! And we actually get along great. He is in the wrong. No need to sit and chill at your exes when your fiancée is waiting for you at home – that’s just bloody rude
Ifeellost22

YTA… dude was seeing his kids and was exhausted. Sure he made a mistake, but either you trust and believe him or you don’t. Either way he probably thinks you are now to much drama for his life and guess what, his kids and the ex are still going to be part of his life tomorrow and now you won’t.
jillandjackolantern

NTA- he got mad at you?!!!
He should have called, not texted when he woke up. And 10 hours is ridiculous.
He tells you to relax? Oh no. He’s gaslighting right there.
You’re a smart and strong woman to leave and not put up with his bs. I hope you kept the ring
anotherworthlessman

He couldn’t call you to pick him up, get an Uber? Cab? Let you know ahead of time he was going to stay there?

I’d give him a pass if it was his buddy Bob’s place, but not when we’re talking exes.

NTA. If my ex fell asleep at my house I would wake him up and make him leave lol 💀 they’re both clowns get yourself out the situation. It’s disrespectful even if there’s nothing untoward about it.

NTA

Unreachable for over TEN HOURS at ex’s place. Something shady definitely happened.

Much respect for trusting your gut and ending things the moment you saw the red flag 🚩

tonidh69

Too tired to text? Lmfao. That’s pathetic. Proud of you for not believing that bs. And being decisive. There’s no excuse for that behavior. Nta

NTA If he was that tired he should have gone home instead of making himself so comfortable there that he’d fall asleep.

Conclusion

The Original Poster (OP) felt deeply worried and disrespected by their fiancé’s decision to stay overnight at his ex-partner’s house without communication, leading them to end the engagement. The central conflict lies between the OP’s need for security, clear communication, and fidelity expectations within a committed relationship, and the fiancé’s insistence that his actions were innocent, driven by exhaustion, and that the OP’s reaction was an overreaction.

Was the OP justified in immediately ending a two-year engagement based on the fiancé sleeping over at his ex’s home and failing to communicate for hours, or did the fiancé’s actions, while poor judgment, warrant less severe consequences given his explanation about being with his children? Should commitment and trust outweigh perceived boundary violations in co-parenting situations?
