D*mn, my stories don't hold a candle to yours
I was once set up on a blind date, and ended up dating the guy for a few months. The guy was a total (insert colorful word of your choice here). He refused to tip cab drivers - usually when we took a cab somewhere, he'd pay the fare and I'd slip the driver a tip. That was the least of his problems... I could go on for *days*.
He broke up with me by IM.

And a few months later, he IM'd me to tell me he was really sorry, blah blah blah, and btw, he was engaged.

!!!!! (They never got married, luckily for her.)
I found out not long after we broke up, that he was on Prozac. And I suspect he hadn't been taking his meds for some time. I can't believe I dated him as long as I did. But I'm well rid of him
