Ok I tried the approach of "Who is this", and I tried the "Ok, I know its you, I'm tired of the games. I'm happy now and I wish you all the best and that you also find true happiness, but please stop trying to contact me."
I have ZERO desire to speak to my ex ever again, so friends, "ain't in the cards" for us. I was the one that wanted out of the marriage because she made me miserable (hitting me, calling me names, etc.), in turn for miserable treatment I was a butt head at times, just for the sake of being a jerk (nothing physical or name calling, I was just hard to get along with). Our families didn't like each other, etc. It was doomed from the start really.
