My mind is having a thought: if I don’t confess all that I did wrong to my boyfriend I will commit the unforgivable sin. What am I supposed to do in this situation?

Tmi warning I was being intimate with my bf and I kept getting the name of someone else pop up, but I didn’t feel anxious. Afterwards, as much as I tried to delay confessing, I couldn’t help it. I confessed. My bf was fine he said I probably didn’t feel anxious because I’ve gotten used to the anxiety and it’s okay, it doesn’t define me any more than it would if I was anxious. A few minutes later, he got upset and said that the confession kinda ruined a blissful moment. I’m so upset that my head feels so turbulent I didn’t even notice it was a blissful moment for him and could’ve been for me. I feel so awful. I haven’t slept in a day, I can’t stop crying. My bf is afraid that because this specific name keeps popping up, it might mean something and he feels less than sometimes because of it. I know I shouldn’t have confessed but I felt so safe that it was like a dam broke loose. I feel so awful. What’s worse is that I’m still scared it means something, I’m scared that my boyfriend’s fear is right. He’s very understanding of OCD and how it manifests in me and everything, I think I just kinda messed up a sacred moment and I feel so much guilt and confusion and just horrendous. I’m not even fully anxious. I don’t know what to do. I apologized a lot but I feel like I don’t deserve him and so selfish

I often feel like i did something wrong even tho i am positive i didn’t, my boyfriend and i have been together for like 6 months and i’ve been completely loyal to him the whole time but recently i’ve been feeling the need to confess that i cheated on him even tho i didn’t and there’s absolutely no proof that i did something even close, i don’t talk to other men and if i do my boyfriend has full access to my phone and it’s usually a friend or me asking a simple question but i still feel the need to confess even tho i’ve done nothing wrong🥲 someone please help it’s so confusing
