What is the % ot trust again on a friend who once cheat you?

I think it's very hard to trust a person who cheated on you. Being cheated on hurts badly and kills trust. Even if you try to forget you can't and, assuming you take them back, years later something can still trigger that sense of betrayal. Also in many cases if someone cheats on you once they will often do it again.

Give a chance..... But beware that he might not do it again..... If u got any such symptoms than dear its better to have a intelligent Foe than a Careless friend.
