I (22f) cheated on my boyfriend (28m) 4 years ago in the third week of the relationship. I came clean 10 months ago and he forgave me. It was drunk kissing on the party with one guy and one girl but I just told him that I kissed a guy one time and that I felt bad about it. I don't know why I did this, why I didn't say everything to him about it. He forgave me and our relationship is really great rn, my therapist told me that it isn't about confession anymore and that I should get past it already but I feel so bad about it. He said to me than that he didn't want to talk about it anymore and that he wants to try to get past that and here we are 10 months ago. He asked me for the details days after that and I was scared and didn't tell him about everything... I am worst person now then before I told him.
