my fiance is cheating on me??

Strawberry it really doesn't matter how you found out. Seriously. That is a minor issue that can be discussed in another thread at another time. What you need to do now is make a decision, based on what YOU KNOW about him NOW, regardless of how you found out! Do you really want to live with a womanizer? In the end the decision is yours, not you parents. YOU are going to be living with him, NOT your parents.

And no, every guy does not do that! Only guys who cheat/flirt say that. Like in every thing else...liars think everyone lies, cheaters think everyone cheat, and so on.
