It is definately hard when people cheat on you, as I have found out the hard way
Shikari bhai, just for all intense and purposes lets just say your girlfriend cheats on you. Would you be able to forgive her, even if she does realize her mistake? If you say yes, you are very noble and i salute you, but think about it. Its the hardest thing to forgive someone who has cheated on you, i partially still havent even though now she is going out with my best friend.
