How did it go for you guys and your partners?
I am in kind of a similar situation.
I was very drink a couple of years ago and kissed somebody else(or we kissed each other) I remember saying out loud, that I had to stop because I had a partner. The next day I felt terrible, but decided to keep it to myself and decided to not drink so much in the future. The problem is now that me and my partner have to go to an event were the other person Will be there as Well. I feel terrible and very anxious and I am thinking about breaking up with my partner because of my guilt. My partner is the best person and the best partner.
