Me and my girlfriend have been a storybook relationship. Never got in arguments, always talked about our problems if we had any, the perfect relationship. It took a turn for the worse when we decided to become swingers in the lifestyle. We had rules about how we did things and everything was working out great until drugs got in the way. I won’t say what drugs were used because I don’t want to be judged but it really messed us up in the thinking process of the lifestyle. While at a club a girl that my girlfriend trusted asked to take me in the back for some one on one. She said yes, her friend grabbed me and took me to the back. Turned out it was a orgy. Her friend acted like I was given the ok to join in and to be honest if I wasn’t on drugs I would have passed but not thinking clearly I participated. That was 10 months ago and no mater what I do wrong she throws it in my face saying I should have known better. She cheated on me 3 times since the incident claming that she did it because of the orgy.  We are not on drugs anymore and she wants out of the relationship because she can’t forgive me. She is my everything, my soul mate, my all. We have gone to couple’s counseling but that don’t seem to work either. Is there anything anyone can suggest that might help me convince her to learn from the past and stop living in it? Thank you for taking the time to read this!
