My ex and baby daddy has a new partner of a year now and has told me their relationship is toxic she’s controlling and when they argue it gets so nasty with shouting in each others faces and things being thrown across the room.. he has been telling me he’s not happy and he wants out so I’ve been patient with our daughter going there for two days one night every week but now he’s telling me he doesn’t want to give up on the relationship so I have told him he can continue his relationship with our daughter but I don’t want her staying there overnight as I don’t want her around their relationship. He has gone absolutely nuts at me and cannot see it from my point of view at all, he shouted at me today in front of our daughter and was vile to me. I simply don’t want our daughter around their relationship I want to protect her and I don’t feel comfortable with it. AIBU?
