Details are irrelevant. Don’t give OP hope. 1/100 times it’s turned around. Even a broken clock is right twice a day. This thing was dead before it started.Well, he said she turned him down. For what, exactly? A date? Sex? Are they still friends? Were they ever friends? Maybe there's another post around here explaining the details, but I haven't seen it.
Anyway, point is sometimes these things can be turned around. I know, because I've down it. When I was younger and randier. I wouldn't do it now. I don't recommend it. But it is possible.
