Gawd, am I tired of these relationshit posts.
If you invited someone out to something, you offer to treat them. That's just called being a decent human being.
Am I the only one who thinks this is far from fair? If you invited her, you pay. If she invited you, she pays. Easy rule. Making whoever you invited pay just because the date didn't go your way is a major dick move. It's as if you were saying "I'm only paying for her if she will repay me with sex later. I literally value her body and intimacy the same as I value dinner."
Kinda makes one wonder if she got the impression somewhere along the way that this guy is full of dick moves and that's why the date didn't go the way he wanted...
