Is NOBODY wrong in the post ? POST : Pretty much title. Overseas holiday and I kissed a girl but left the situation immediately afterward. Reconciled this by thinking I’d done the right thing by not continuing despite her wanting to do more. Returned home and nothing was spoken of it. 

Several months later, she comes to me crying and confesses to me that she had kissed her ex-boyfriend at a nightclub when we were going through a particularly rough period.  She was clearly upset and reinforced she had no feelings for him and had regretted it ever since. 

Following this I tried to be supportive, however, I found it extremely difficult to come to terms with this - especially since she had continued to put herself in social situations in which she had known he would be there. We took a little bit of time apart before I eventually told her that I couldn’t go on with the relationship knowing what I know. Adding to my decision was the fact that she had had a track record of cheating on a boyfriend before. 

I definitely feel guilt in the aftermath of the situation, given that she had the courage to admit it and I hadn’t. In the months since our breakup she has already found another partner which has made it tougher. At the time of finding out, I did not even consider my own cheating to be anywhere near as serious and have only realised recently how hypocritical this sounds.
