Inspired by another thread. My ex boyfriend started seeing someone just after we finished. We have 2 kids together and he won’t go anywhere without his now wife. So he doesn’t come to school plays, religious events or anything. He wanted to see my son on the first day of school 2 years later but I said no because I knew he would rock up with her. Aibu to just not tell him when anything is so that he can’t bring her too? He showed up once at a sports event and brought her. I couldn’t cope seeing her and I never want to see her again.
