My ex won’t leave me alone

Ok so I was seeing this guy for a few months then I found out he was married. I cut ties with him. Blocked him from and on everything. I even moved states. He still contacts me and ended up moving to the same state I’m in a (few hours away though ) for work. Mind you he had a whole ass baby with his wife. Yet this piece of shit still tries to talk to me. Telling me he doesn’t love his wife. He wants me. Tries to apologize for everything. Promises that he’s gonna figure a way out. Something in me just wants to tell his wife already so he can leave me alone. Wtf do I do?!?!
