He failled to tell me he was in a relationship with another girl and she’s pregnant as he was trying to get back with me…we went out on a date, even though he cheated on me he told me he was a changed man. I am hurt that he chose not t tell me this and I had to find out otherwise…how do i forgive myself for going out with him…he has a girlfriend and she’s pregnant!!! and I had no idea…we only been broken up for 10 mos an he started dating her when we broke up for 4 months come to find out…I just feel so weird ….
