Sexual life exposed.

When I was 19(I’m 22 now), my best friend and I were very close. She would tell me everything, even her sexual experiences, I barely had any though. At the time, my now boyfriend and I were friends, we decided to be friends-with-benefits at the time. We met up, did things and I was excited to tell my friend. I told her what he did to me (may I mention what he did is not accepted in the eyes of men in my country). 3 weeks later my boyfriend and I made it official.

With my new relationship I kept everything private between us and only us. We all went to the same school and my friend made some friends with some guys. Recently my boyfriend said his friends are asking multiple times if “he has ever done (said action) to me”. My boyfriend denied it but his friends kept asking and saying they “heard something.” My boyfriend is a very private person, he doesn’t tell anyone anything and when we were friends, I did not know that, only when we got together and I learnt more about him. He asked me today if I had told my friend what he did to me. I answered horribly and didn’t tell the whole truth but eventually it came out. He is very upset, I told him I want to confront her but he won’t let me, saying it will cause a domino effect. He wants me to expose something about her but I can’t even talk to her. I feel bad that I gave him that embarrassment and I truly thought I could’ve trusted my friend. If it’s getting back to his friends it would have spreader somewhat amongst his circle. It makes sense because his friend is friends with one of her friends. My best friend even told me once her friend told her “my boyfriend said wanted to get me since high school” which means she have definitely spoken about us before. I don’t know what to do my boyfriend is very mad. I hate her if she did this, this is the best relationship I’ve ever had and we just came out of a rough patch. My boyfriend feels like he can’t trust me now because I told his business when we were friends. How do I go about this my boyfriend is so angry he wants me to expose her secrets too. I don’t want to make any rash decision and I’ve just never done something like that before, she was my only friends.

*May I also mention that me and best friend don’t talk as much because of covid and just different interest. We still talk a couple times.

* Also add that since I decided to keep my relationship private my friend has been acting weird and would randomly ask me specific questions about my relationship and my boyfriend, she also was offended I wouldn’t tell her about issues in my relationship.
