Harman, Forgiving her is the best idea, but that doesn't mean you have to be with her. It's just not worth to continue your relationship with her anymore. What's the guarantee that she wouldn't do that again? How often can you forgive her or how often can you go through this again? Believe me, the more you love a girl and forgive her, the more she will continue hurting you. To love her at this point means to show that she is your weakness. That's the worst thing you could do, let a girl know your weakness. Forgiving for everything makes you a human, not being with her again makes you a man. Don't fight, don't hate, just leave. People are commenting that it may be the emotional thing or the sexual desire that you may not have fulfilled. Believe me, if you can't fulfill it now, you can't fulfill it again. Finally, be with her if you want to live in pain. Forgive and forget if you want to live happily. Jai Sambhu, Om Shanti, Shanti...
