I am 34 and have been with my partner for 14 years. Early in our relationship after the inital falling in love, honeymoon period we went through a really rough time. Much of it was my fault as I have terrible self esteem issues and sought validation from being found attractive by men. My life pretty much fell apart in my early to mid twenties due to my own health issues, family illness, dropping out of uni, giving up on a longed for career (self esteem issues again) and massive weight gain. I was very depressed and in therapy and on antidepressents at the time but did not talk to my partner about it. At the time I felt he was cold and uncaring but looking back now I can see I shut him out and its a wonder he didn't leave me then.
Unfortunately at this time I developed feelings on a friend of his, this guy was also going though a kind of break down and I kind of felt only he could understand me (stupid) and I wanted to save him, I wanted him to validate me. Anyway we were rarely alone together but he must have picked up on my feelings because whe we did end up alone after bumping into each other in town at night he kissed me and I let it happen, we went for a drink and he said he wanted to have an affair with me and I agreed (cringe) our affair ended up lasting that one night only with us having sex in the street :( after this he basically ignored me while I continued to believe we were meant to be together for about a year!
Anyway that was 9 years ago now and my partner is still friends with this man, they play squash together and ocassionally we see him and his wife socially. We both pretty much avoid each other.
I am mortified by what I have done, I did eventually buck up and realise what a great guy I have and our relationship is great but I live in fear of what I did all those years ago coming out. I don't know if my partners friend ever told anyone else, maybe once not long after it happened another friend made a comment to me which maybe implied he knew but I was very paranoid at that time.
If I could take anything back in my life it would be that. My partner would be so hurt and upset if he found out as well as humiliated.
I don't know what to do about it, it casts a shadow over my current happiness but perhaps I deserve that. Sometimes I think I should leave my partner because he deserves better than someone like me.
Has anyone else been in this position and what was the outcome, how did you cope?
