So stay away from these types of girls, and don't settle for any less respect than you deserve. There's a trade-off to this approach. If you lower your standards, it'll be much easier to meet *any* girl and take the chance that she might disrespect you and hurt your feelings. If you keep you standards high (for many people, demanding the respect they're worthy of is a hard standard to maintain), you're going to filter out *many* girls and meet worthy girls less often. It depends on what you want - quantity or quality?
Lots of girls feel the same way about meeting cheating adulterous guys too. Try not to be one of those guys, so when you do meet an awesome girl, she won't be scared by your history either. Good luck!
Well just because girls date after a breakup immediately doen't mean they are over you or characterless....it's a way of hiding thier emotions and feelings, they date so soon in hopes of getting over the other guy sooner....I was one of them and really it's not right to rebound because it usually hurts someone including yourself in the end but sometimes that's just what girls do...although I have never had an affair on any of my boyfriends....that is just wrong but guys do it too....it's just a lack of responsibility and immaturity....affairs are selfish and can really wreck a persons feelings and esteem but when your young you want to experiment and your not really into looking for the right guy and settling down at the time your more into just having fun while your young :)
