I was at a party a couple of weeks ago and I went with my girlfriend just a gathering of friends. I went to go help out my friend with something and when I left my girlfriend was getting fucked by the other guys there I just walked in on them she had a video camera out and was being filmed this entire time. I was shocked she is a girl with strong Christian values and we met at church she said she was saving herself for me until we get married. I just left after seeing that I felt betrayed by my friend's all having sex with my girlfriend behind my back. She called me many times and I didn't answer. Now she's saying she's sorry and how I shouldn't of left her there because she had no way of getting back home. Did I do anything wrong? Should I forgive her or is it not worth it?
