AITA for not inviting my ex-wife to my wedding, causing my daughter to not show now?

I can’t understand why everyone is concerned about his relationship with his EX WIFE. I mean, it was great that they were friends and all but they’re exes for a reason and there’s no need for her to be an intrinsic part of his life outside of coparenting their child. The truth is that Claire is now his soon to be wife and he MUST prioritize her feelings over anything that his ex wife might feel. How would any of you feel if your partner was still living with his ex? If he was super close with her and always talking and hanging out? It’s not something that simple to accept.

Now, regarding his daughter he’s being TA for just giving up without a fight. He could explain to his daughter and his ex that he and Claire are not comfortable having the ex at the wedding. They don’t need to make excuses and truthfully it’s their wedding and they get to invite whoever they want. However, he should talk to his daughter about how Claire isn’t trying to erase her mom. Either way, if his daughter isn’t at his wedding that will be something that she won’t ever forget and will deeply affect their relationship for good.
