I think your banter is pressuring him and he's backing away. You've let him know how you feel now let it go. You're still trying to get him to see how much you've changed.
Let him go, let him be who he is.
You may decide that what he has to offer isn't enough. That's a scary place to be but you can handle it.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
