I (22F) cheated on my finace (27M), dating for 3 years, and kissed a girl at a halloween party. I have never felt the urge to cheat or have had any issues in past relationships with cheating. I had been heavily drinking which I definitely don’t use as an excuse but mentioning here for context. I have told him and we are working on it together but I feel so disgusted with myself. He has forgiven me but I don’t think I will ever be able to forgive myself. Has anyone ever experienced a situation like this, on either side, that you were able to work through it and your relationship go back to “normal”?
tl:dr: i kissed someone at a party, we have talked and i have been forgiven, but how can i forgive myself/go back to “normal”
