Insecurity And Relationships .

Rule#1: if someone wants to cheat, they'll cheat no matter how hard you try to stop them. Therefore, learn to let go and let people do whatever they want. If they do something you disagree with, talk it out. If no agreement can be made ->breakup.

Rule #2: Insecurity is the biggest turn off for either sex. It stems from thinking "you aren't good enough." It's a life lesson, but when you learn to value yourself, you'll stop sweating the small stuff and realize that you are both lucky to be around one another, and not the other way around.
