Input: TLDR: I despise my mother’s boyfriend who has not treated me well and do not want him in attendance at my wedding. WIBTA for not allowing my mother to bring him? 

Basic backstory is that my mother and father separated when I was around 12 and have both since found new relationships. It wasn’t the messiest divorce, but by no means was it amicable and I was very angry for how it went down, especially in regards to my mother, for quite a few years. 

At this point, I’m 21 and have a wonderful boyfriend that I’ve been with for over a year. We’re living together in his country while I do university here and it’s been going well. We‘re not engaged, but we’ve spoken about it and it’s just a matter of when (I’m not pressuring him).

I despise my mothers boyfriend. My mother didnt handle a new relationship with this person and her children well. She moved him into our house without any regard for my or my sister’s feelings. We were just ambushed one day and told that he and his disabled mother were moving in. I admit that at first he attempted to form some sort of relationship with me, but when I didn’t bite, it became mutual ignorance. He then began to erase every semblance of my father from that house. He destroyed our pool, he turned my sandbox into a pit for his cigarettes, he painted over the mural that my father painted for me, etc. 

I never left my bedroom because I was so uncomfortable in the house and barely spoke to my
mom. The only time I got with my mother was when we would watch this one show every week. Once when we were watching this show, he came in, grabbed the remote from me, and told me about how I was such a terrible child who didn’t respect my mother or him and I needed to get my act together and then threw the remote and stormed out. I never again watched that show with my mother. 

After I went to university, things got a bit better with my mom and I worked on forging a relationship with her that didn’t involve him. And things are better now. We hang out and talk and I’m happy to have her in my life. But I will not go to anything if he is involved. To be honest, I don’t really care if she feels bad for having to pick me or him because I was never picked when I needed her when I was younger. She says I don’t want her to be happy, but I believe that incredibly selfish to say and I don’t want to deal with it. 

Anyway, here’s the basic question. I told my boyfriend that my mother could not come with him to our wedding. He doesn’t think that’s fair to her as he’s in a very similar situation with his mother and her boyfriend and that I should want my mother there no matter what. He tolerates her boyfriend and speaks to him because he loves his mother so much, but he doesn’t like him. I don’t want that. I don’t want to feel this hate inside me when I’m supposed to be my happiest. So WIBTA for only allowing my mother to come without him?
