Is AUTHOR wrong in the post ? POST : To begin, this is a fairly new relationship. 
My boyfriend and I are in the same social group and I found out he had told two members of our friend group what we had done the other night. 
This had happened a couple weeks before as well and our friend told every other friend in our group. I had told him how I felt about it and explained that I didn't care if they knew everything else about our relationship, just not the details of our sex life, I feel that should just be between us. When confronted, he said they were close friends and that he can't hide anything from them. 
AITA reddit?
