I can understand the hurt that your ex wife is going threw, but she also needs to go to counseling and see that she doesn't need to shoot you with a invisible gun every time she sees you or talks to you. What I see is a soul Tie, are you two still sexually together? If so, that can be some of the reasons why she is still emotional.

I know the feeling of a man who shows dishonesty and un-loyaty, but I moved as far away from him as I could. He was a infection in my life and not saying that you are to her, but maybe she is to you. It only takes one adult to make the choice...You have to be considerate around the child, but to entertain the argument or behavior is another...Keep it in the courts...When emotions rise, is when hell begins...

You already knew you messed up, so now it is time for you both to just heal....Maybe if you want something more, get canceling or even CHURCH canceling...God bless you hun, and I truly hope one day she will realize that this energy can be directed to more to positive things...
