I'm sorry for all the questions, but it seems lately I have a lot of them..

Why is it... that whenever I tell him it's over, he calls me bluff everytime and no matter how mad I can sound, he STILL knows I don't mean it...

Yet when he tells me it's over, I believe him and I get upset and emotional, and then a few hours later he'll call and tell me that he doesn't mean it and that he'll never really leave me.

How come I always believe he's telling the truth when he's leaving, yet when I do it... he never believes me?
