James -
HAHAHAHAHAHA.....does this have anything to do with that "Ned" email I sent you?
No this isn't fair because - I look at some of the guys I dated and it's like looking at the fashion mistakes in my closet. "ACK! What was I thinking??!?" We all grow and change and make big ole blunders. Even though I dated some jerks, I would never say I'd like to take it back because I learned something from each relationship and if I hadn't I wouldn't be where I am now.
But if you're talking a woman who makes a habit of dating men who beat the crap out of her, that's something else again. Unless you want to be an unpaid psychiatrist, being her friend is the only commitment you should make unless you enjoy trying to talk people out of self-destruction.
