Man, you really need to listen to the valid advice you are getting here. I mean can't see that you are only focking up your current relationship. Leave your ex aka "the friend" the fock alone. Ask yourself this question, "Do I really love (insert name)? Do I really want to mess things up with her, over someone that cheated on me in the past?" I understand what you saying though. But, be real man. My ex cheated on me, and she tries to this day after 2 years to be my friend, hell she wants me back ( and she is married now). I ignore that b!tch all I can. Just don't lose what you have now for someone from the past. That's just my two cents.
