I had an interesting experience the other day.
My ex is actually crazy, like diagnosed borderline and genuinely afraid of crowds and the public, absolutely no personal boundaries (if you she could see you, you were in her face) and she smoked pot every day, wouldn't eat for days at a time, and sometimes cut herself, and had had many abusive boyfriends (whom she would still talk to on the phone, god knows why), and tried to get herself raped (methodically seducing her married teacher [telling me the details along the way, I thought it was a strange thing to do] and then he fucked her on his classroom desk until she freaked out and stopped him in the middle of it and went to a fucking police station) and I turned into a real downer myself around her.
She IM'd me the other day when I got a new AIM client and forgot to use a block list... she still has my username in her freakin' buddylist (don't forget, she still talks to even some of her abusive exes) and would try to talk to me. I guess she still smokes pot every day because her message popped up on my computer screen:
"Who is this?"
So beautiful, she has forgotten about me a little more.
