Look what you are going through now you are persuing and its getting you no where.
I know hard it is when the wheels in your head keep spining.
You have said it your self what happens when you stop with the contact.
Go to the event have a good time.Dont inform him on it just keep it to yourself if he asks just say "fine" and leave it at that.
In my opinion you expect him to come runing but thats IS NOT HAPPNING.
You are the one running when he calls!
You have to learn to detach.
Im going to quote SANDI here
Its not doing what you think that works but doing the things that do.
