dont even think on him or her cuz he or she not deserv to even think

This is not your true friend at all. Ask them why they did this to you, or if you are too upset send them an email or sms.If they won't explain, I would not have them as a friend anymore.

Oh,thanks for sharing me this question,Genevieve~:) hehe,well,I think it depends. I will make it clearly at first that why he or she cheats me.for what reason?Is it severe? If the friend hurts me badly and on purpose,maybe I will not forgive him or her... but however...it happened before,but finally i forgave her.She made me upset and disappointant.I hated her and cold to her once.But when she was apologizing to me,I felt that I should give her a chance to be honesty.I think that she was really regretted what she had done to me and after all,we had knowned each other when we were 7.So,yes,we are still friends now.I view important on our friedships. I have many friends,but not every one is true friend.I am not like some ones who called everybody as their friends when they met others. I love my friends,if one day one of them cheats me on my back,I think I will be very sad and don't know what to do.Break up with him or her?Maybe that's a good idea....but I will be painful after making the decision.

actually, i don't know what to do if it really happened.but as for me, i think it depends, depends on their place in my heart. if he or she in my great affection, i will be consider forgiving him or she.

maybe he have some secrets or problems one doesn't want to reveal .but deception is a shameful act.If he apologize, I will forgive him.There is a Chinese old saying goes"To be able to mend one's ways is the greatest wirtue.To err is human."
