Well Cisco, It seems you’ve gotten tons of great advice, so let me be the first to give you what I’m sure is bad advice, but hey it works for me…somewhat.
First of all I think we’ve all established that she was crazy. I think this is shown through the fact that she was (as I got form your telling) a great lay. In my experience crazy women are great in bed, I can’t explain it. It just is what it is. Ok so now you have a crazy ex, great. No big news there.
“How do we deal with crazy Ex’s?” I say
“Well O.J. tried killing his.”
“Interesting” I say. “You’re thinking, it show initiative, I like that.”
“The cut Gordian knot approach; how very 12th century BC.”
Alas murdering ones ex is the one of the fastest ways to become one of the Butt Brothers of D-block, so I think you might want to try again.
“Well O.J got away with it!” you cry
“You are not OJ. OJ was famous. You are not famous; you are a nobody. Nobodies go to jail and learn how to spoon with hairy bikers and angry bald white guys.”
“But I have a loser free loading friend who can testify on my behalf.”
“Do not anger me.”
“Could I try mindless juvenile pranks?”
Now we are getting closer
Juvenile pranks are a great passive aggressive way to strike back at people in a very amusing and demented way. I recommend prank phone calls at random times of the day, where you press buttons every time they try and speak.
“But how will that make me feel better? Will it erase the pain in my heart or soothe my tortured soul?”
Hell no, but damn if it aint funny. 
Now we move on toward step two: Moving on.
This is the part that I know I’m going to take a lot of flack for, but what the hell.
Become a total asshole. Go out and get laid, I mean really go get laid. Take every opportunity you can to get a warm body into your bed. It helps if they look good, but don’t be picky at this point. The main thing you need to do is reestablish your self esteem. Become that guy woman love to hate, mostly because there is only one person you need to take care of right now, and that’s you. You can lie and deceive woman if you want, but trust me it’s just too much trouble. Just be honest, and let them know as 50 cent says you’re looking for a slut with a nice but to nut. Yes I know, it’s all screwed up, callous, unfeeling, and a hundred other things. BUT, y have to pick up the pieces, figure out what mistakes you made (in this case letting her push you around) and move on to the next new thing who hopefully won’t rip your heart out
“Man you are one seriously F’d up individual!”
“Bite me, its cheaper then therapy! :smack:
