Why so angry, Savage? The letter doesn't specify what the girl was into early in the relationship. Maybe she just doesn't want to get peed on and this is a big step up for her. I don't think there's evidence to suggest she was manipulative or dishonest. Maybe she's just not as into him as she was in the beginning. It happens...
DTMFA? This seems like Savage 101 here. You told her what you want/need, she isn't open to it, you aren't going to therapy, move on.
