Too much inner dating can be bad for your social health.

I don't know but it seems like the pool of women that are available to date has dwindle to a mere few that haven't dated a friend of a friend or something like that. This weekend was a good example of that. Someone I dated 3 yrs ago is now dating a friend of mine...it ended in a bad way and she had a reason to not like me or be mad at me but its been 3 yrs and she's dated someone the whole time during that. I was the best man at this wedding, she really shouldn't of been there not because of me but for the mere fact that she's a two faced judgemental bitch. I didn't acknowledge her the whole day because I have nothing to say to her, we would talk online and then she blocked me, every time she has a opportunity she brings up old shit or says bad things about me. So how am I the asshole for not saying a damn thing to a person that bad mouths me? The fact that my buddy asked me if I would be uncomfortable with her coming and I said no because I don't want it to be about me and her should show some fucking maturity. I'm not fake, so there is no sense in going through a charade. I kinda reacted in a very explosive manner but its just a summation of things that I've had to deal with, its just gets to be too much. You don't want me to talk to you but then you do? WTF?
