first off, you have to clarify one thing: are you guys looking to score or to be in a relationship?
If you're looking to score... who cares if she cheated before! It just tells you that she loves sex, and you can start talking dirty to her right away (usually all girls like to talk dirty... sometimes in the whole process of dating).
If looking for relationship... it doesn't mean that she'll cheat again! Why did she cheat in the first place? Was her ex a cheater too? Did they have an "open" relationship? You'll never know until you ask her. And if she's really a "plain ol cheater" and you're looking for a relationship... fuck her. NEXT! I find that guys who are looking for relationships are a bit more skeptical about girls. And if you can't handle the stress of knowing that she might cheat... forget about her. However, if you demonstrate higher value, she'll likely stay with you. Keep her guessing about YOUR situation. Keep her on her toes at all times... they love that. Most girls like the unknown - it keeps them going, makes them hold on to their man. Show her you got game... show her you have confidence and that she's not the only one out there. I assure you, that will make her question herself and YOU'll be the one in control.
Good luck to both of you!
