Ex Banned Daughter From His Wedding Over Communication Is…

I (F26) broke up with my ex/daughter’s dad (25M) 3 years ago. we were together 5 years, had our daughter (6F) after 2 years together. good coparenting & don’t really talk about anything outside our child. He‘s been dating fiancée (25F) for almost 3 years. he didn’t tell me about him dating her, my 3y/o did btw.

things changed the fiancée announced their engagement. I ONLY knew bc I saw it on HER social media. She & I have been friends on social media for over 10 years, but ex and I aren’t friends. Right before this, he told me that he could not financially support his daughter for “a while.“ He pays “child support” but we’ve never gone to court. He told me it was because he was moving into a new job field, I said that’s great and fine. days later, I open my social app to see an expensive looking ring. I was annoyed but things were civil, so I said nothing. fast forward a month later, his mom texted me to say she would take our child on his days, but not ALL of his days. He texts me after to say that he was busy. it’s less than 24 hours before he was supposed to have her, so I figured something must‘ve come up. I made arrangements to be home instead. It was only until a few days later that I started seeing vacation photos on his fiancée’s Facebook.

next was word vomit. when his next time to have our daughter came, I let him have it. I told him he could have let me know in advance he was going out of town and that he had to have known for weeks ahead & how disrespectful he used his mom to communicate instead of coming to me. I said it’s a pattern, he also didn’t tell me about his plan to marry & that involves our daughter. His response? His fiancée wasn’t getting any legal rights to our daughter, why did it matter? I asked – Is it important for our daughter to gain a step mom? Is it important that YOU tell me about important things going on in our daughter’s life? the conversation really went no where and his fiancée then blocked me, which spoke volumes – “not only do we think you should’ve found out like this, you shouldn’t have found out at all”.

In the end, I told him our daughter wouldn’t attend his wedding. As far as she knows, the reason she isn’t going to the wedding is bc we have a trip planned for that day, & they don’t even have a set wedding date because they are due with a new child now. I‘ve raised our daughter almost solely, even when he and I were together, I’ve been there for all of her important events, & I fear he’ll go behind my back and I’ll miss seeing her at her first wedding (and even potentially being a flower girl for the first time). I would not be able to help her dress, or do her hair, or see her walk the aisle, all which mean a great deal to me to be witness to.

please tell me, AITA? my friends tell me I’m not, everyone else says that I’m being selfish and punishing them for no real reason, & his family says I’ve caused them to postpone the wedding, I feel bad but I still am firm in my decision.
