I once had an actual therapist chastise me for sleeping with someone at a conference. Not only was that person also single, we had a great time. But the therapist was disappointed, clucking about how we wouldn’t ever have a relationship. I actually had to tell her I wasn’t trying to husband the guy, but if I was, and he was dumb enough to be THAT guy, our relationship wouldn’t have a chance anyway. Still friends with conference guy, but I broke up with the therapist immediately.
