My boyfriend still talks to his ex and recently found out she sends him nudes and he saves them. I told him I didn’t like what was going on. He kept on chatting with her and exchanging nudes. Every-time I bring it up, it turns into an argument and I have to apologize to get everything back to what it was. Yesterday I gave him an ultimatum that it’s either he blocks her and delete her from our lives or loose me. He said he’s sorry but he can’t do that, he cannot block her out of his life and that’s also his ultimatum. Am I wrong if I decide to leave him or should I stay and make this relationship work.
