It seems to me that every guy that bitches about a girl has one of two problems (or both):
1. has no game
2. has no confidence to move on and instead, bitches about her and makes excuses for why they aren't together (she is a bitch, she is in it for the money, she is a snob, etc).
If you have "game", chances are that you have the self confidence to move on when a girl doesn't go for you. Someone that is confident wouldn't care. Instead, they would move on to someone else and it would continue like that until they found someone that they really liked/wanted. Those that get rejected and bitch need a self confidence refresher course.
MOVE ON and stop harping over the past. It isn't worth it. There are PLENTY of women out there! Keep moving forward and stop looking backwards.
