A lot of 'nice guys' aren't. They're borderline creeper / stalkers who go out of their way to sabotage their unrequited's various relationships when they should have either: a) nutted up and made their move before they became as familiar as wallpaper, b) threw up their hands and walked away a long time ago, or c) actually figured out how to be a real friend to the woman in question. So basically, f*ck them.
"A lot of 'nice guys' aren't" ...and you know this how exactly? You conducted a study? You have data to prove your drivel or are just speaking out of your ass and dumping useless facts on us. Do you really know what a nice guy is vs. what you think it is?
I agree with the " They're borderline creeper / stalkers who go out of their way to sabotage their unrequited's various relationships" this holds ground for the ladies also although I do not believe it is a majority.
Actually to be nice is to tell them how it is or how you think it is even though it may hurt them at the time or end ever seeing them again. This would be considered a nice guy, and not some fake pussy bitch white knight just saying shit to get her approval.
There is different levels of nice guys. There are also those wolves, weirdos, creepers, sociopaths and psychopaths trying to disguise as nice guys. Its quite easy to sense them out actually.
You have not convinced me I still see value in being nice to people. I don't think it is that bad.
I consider myself a nice guy overall even though I have my deamons and cheat on my wife with MPAs sometimes and think by doing this it helps me be nice to her and overlook the parts I need from her. Overall, she is a nice person, is happy and content minus the intimacy, so why ruin it by telling her the truth that I need it more then a couple of times a year thus I see the MPA. Does this make me a fake pussy bitch white night? Who knows, I dont think so, but others may see it different. Sometime you need to pick and choose what you disclose to them, none of us are 100% honest, this is not possible. Simple test is to ask yourself how many times have you seen her happy, how many times have you made her laugh, or saw that she is content living with you vs. how many fights have you had how many times have you seen her crying because of you. Its easy to tell if she is happy with you or not just by observing her. If she was not happy overall I'd leave and try to do it on good terms. Now she tells me and shows it to me, and its all I need.
I think nice guy means respecting people, not trying to use and manipulate people, unless they give you an excuse or try to fuck you over first. I see no point in being nice to people who try to use manipulate and control unless you see hope that its worth your time investing in someone despite the fact that they may be aiming for your throat.
Thus like I said there are different categories and levels of nice.
