This is one of those times that I think you living a better life is really the best revenge. He seems like a person that does all these things just to see if he has control over your emotions. Dangling you around like a toy and changing moods all the time. Seems very self-absorbed and just wants control over you. I think the more he tries these things and the more you resist, it will drive him insane. People like this cannot stand to be ignored and if you do that, that will be the best revenge on him. Because sinking to his level and throwing something in his face is exactly what he wants - he wants to drag you down and make you miserable.

I know it's hard to do but I think if you stay away from him, and keep contact to an absolute minimum, it will get easier over time. Good luck!!!! And, yes, you are DEFINITELY better off without him.
