It was supposed to just be a mercy fuck. I thought we'd clarified the terms beforehand. I specifically asked if he wanted a one-night stand. If you use the phrase "one-night stand" and the other person agrees, shouldn't that mean you can trust them to keep it casual? I mean, I was specific. I even mentioned "casual sex" at one point. I don't know when he decided we were in a relationship. This is pathetic. You try to boost a guy's self-esteem, and then suddenly he thinks you're gonna be together forever. This is what I get for being generous.
