Girls are icky because they always fucking break your heart. You'll never be good enough for them no matter how hard you try to be. No matter how much weight you lose, how much you work on your image, what new, better-paying job you get or how much effort you put into making them happy they'll always wind up leaving you for another guy just because they can. They'll just blame you for causing the break-up because they "weren't happy with you" even though they're the one who you caught cheating.
Unless you're a homosexual or make shitty friends a man will never do that shit to you. Guys don't do evil shit behind your back. They don't gossip about you when you're not around, if they got a problem with you they'll tell you.
Guys don't pretend to be friends then hate each other when the other is not around, they just fucking hate you.
They don't try to stir up or sit in the middle of drama, if they don't like something they confront it. And they don't fucking ruin a group dynamic by dating one of the group members, ruining the group forever by forcing people to take sides once that relationship ends badly.
I hate to sound like some sexist red pill cuck but that's just from my personal experience with women. I'm sure there's many of them out there that don't fit this description, but I've yet to meet them.
