It matters not whether you win or lose; what matters is whether I win or lose.

I wouldn't do it, Shinto. Even if she never cheats on you again, you'll always be paranoid. Then she'll get overly defensive about your well-founded paranoia, and she'll start leading you to belive that maybe she is cheating on you. It will only end badly. Just walk away.

i agree.....isn't there another person you want to go out with?? her sister, her best friend?

You really think if you forgive her she will have any respect left for you ? She will know that she can do it again.
If you stay with her it's gonna be nothing more then trouble.
Make out with her, have fun then kick her out.

Find a different girl, and the other one you were telling me about, use her just for fun, dont get into a relationship with her. She scares me.
