Moving out w a bf

A couple months ago my family and bf all moved into a bigger condo.

My bf and I fight and he likes to run and talk about it to my mom.

I feel like he got real comfortable and is trying to get close with my mom when I’m really not that close with her. So it is a bit bothersome.

My cousin and brother have gf’s come over and he wishes to interact with them but knows that I’m not comfortable like that cause I don’t even interact with them like that.

I asked him that it would be nice for us two to move out on our own someday and he said he doesn’t like not having people home. And That really didn’t sit well with me. I don’t feel that he’s all about me but more for himself and his own connections.
