I think its equal. I've been around some mean dudes.
Probably girls because either we don't want to hurt your feelings by saying "I don't like you" so we just stop talki to you altogether and hope you get the hint, or we just flat out say "sorry I'm not interested"
I don't think guys reject girls lmao, girls like a guy and find out he doesn't like hem back and then leave him alone lol
Equal probably. Women get hit on a lot more so they learn how to reject people more politely, but then they probably reject harshly because eventually it gets irritating or because some men are really persistent and they want them to leave. Men don't get hit on anywhere near as much and as a result don't learn how to reject people as it often comes as a shock that we even got approached in the first place.
