Am I wrong?

The father of my child and I are trying to work things out and get back together but every time I say anything he jumps down my throat. Yet if he says something that pisses me off ( like him having a nickname for a woman he use to date, whome he still talks to and when they talk they call eachother the nicknames they called eachother when they were dating) F*$K YOU, you don't do that. You break up and you stop calling that person by the nickname you gave them. If you still talk once and a while what ever but for both of them to constantly comment on eachothers stuff and call eachother nick names.

Am I wrong? Like are there women out there that do this with their ex's? Or talk to their ex's all the time?

So much of what he does doesn't seem like a faithful person.
