They seem to never blame themselves for their own failures.
To me, it's like listening to Gaston from Beaty and the Beast:
"Gaston was EVERYTHING a woman/man could ask for: Incredibly nice! It doesn't matter if I was boring, clingy, annoying, and had nothing in common, I WAS NICE! Gaston deserves sex and a date! But noooo, the opposite gender is too STUPID to know a good person when they see one!"
Why doesn't it ever occur to them that Bad Boy/Girl vs Nice Guy/Girl is a false dichotomy and people look for a lot more traits in a lover than just how kind they are?
I would choose to date a jerk over a nice guy if he had the trait I look for in a man. I would have a better experience dating a jerk who's funny, smart, shares my interests, and can make interesting conservations than a nice person who's dumb, boring, and I have nothing in common with him.
The question was about nice guys and nice GIRLS
Most Helpful Guy
A: They've been taught for years erroneous information about what girls like. So they've tried really hard to be what they were told women wanted. Not only that, but they were told that women who didn't want that were not 'nice' girls. So their initial reaction is, when women regret them, those women must be the 'not nice' girls. It takes a while for them to realize none of the girls are 'nice' at least as they were told, and in fact they've been wasting their time for years (decades) and being miserable for no reason.
B: Eventually I think for most it does and they break through it, but having your worldview shift takes some time and is a little painful, and its nice to come online and rant about it while that's happening, which is what you see. Its probably a good thing - in my day, I think most guys didn't realize that being a 'nice guy' didn't work till they were married with kids ... like me. If these guys can get sorted out at closer to 20, that's much, much better. The problem is I'm not sure they've 'bottomed out' on their old world view yet.
