Dear Lovehacker, In the third year of my marriage to my husband, I slept with his best friend. It wasn't emotional. It happened once and was a culmination of several factors (finding my worth through the male gaze, thinking that I needed to test his love for me by hurting him, several other small reasons that don't really matter in the end). I told my husband a day or two later. We stopped communicating with his friend but my husband stayed with me.
Fast forward to present day - we're on our 13th year of marriage, have a seven year-old son, and a nice, comfortable, loving life together. I can say without hesitation that we are BOTH very happy with each other. But it's recently become clear that he hasn't fully forgiven me and I'm worried he never will.
