My bf said something to me that turned me off and I’m about to panic

S-so uhm my bf (?) and I have been a little distant and his spotify yesterday was the same where it says that he's my future husband, and today, it was changed. L-like, i-is he g-go-gonna break up with me??? I'm so scared I'm nauseous and I don't want this stress to cause another seizure, but also kinda don't care at the same time because it would ha-have to be my fault??

I told my boyfriend last night about all the times that I thought I “cheated” (I have ROCD) on him and he said that I didn’t but he still feels uncomfortable about it and I can tell he’s not answering me and he’s being really dry and his responses. He said it was fine but now I don’t know what to do because I know it’s not fine. I didn’t cheat on him, but I felt like I did and I told him that and I think it made him really uneasy. I just don’t wanna lose him and I’m scared because I had a dream about it and he got really mad and broke up with me. I didn’t want to tell him what I was going through in the first place, but it was eating at me so badly with the guilt I had to confess. I don’t know what is wrong with me, but I cannot lose him.

I've opened up recently to my boyfriend about my ocd itself: he knew I had it, just didnt rlly understanded it. Today, I was feeling really awful because of my incest ocd, and the toughts were awful, so I decided to open up. BAD IDEA! he said it was ok and stuff but he also said he did not understand: he is, fairly, disgusted. Plus, he knowns my relatives, which probably made him even more sick. Im so sad, he is now more disgusted by me, and I am too.
