So back story bf and I were together for almost 3 years and then we broke up for about a year in that year I lost myself and last December I got tested for everything and I was clean then in January we started talking again and by February we were back together before we started talking again he told me he had slept with only one person (I was his first) and last week he thought he had a uti so we went to the doctor and today he said he has chlamydia and I told him idk how he got it because I’ve been clean and I asked about the girl he told me he had slept with and now he’s saying he never actually slept with her cause he didn’t feel comfortable and I know he’s trying to blame me for this and play victim but I truly don’t know what to think or do

Does anyone have advice? Or have been through this before?
