Im trying to digest the statement above. I think what you trying to say was you cheated in the first 3 months of the relationship. If I am right, I guess you get what you deserve. This girl is doing what you were doing to her....!

This relationship isnt going any where mate. If she wanted to be with you, she wouldnt have entertained this guy and made it public on FB. From my own experience, there is no way a relationship can get stronger once there is cheating going on. Best you end it before she does.
