Overanalyzing ?

Hey ! So I do have diagnosed OCD that comes in waves of good and bad. My current fixation is ROCD. I went to the bar and got a little drunk and I heard guys talking about the NHL on my way to the bathroom. I then just proceeded to share my (unwarranted) opinion on specific NHL teams and then I was on my way. But now I’m freaking out tha I “cheated” on my boyfriend by doing so. Why do I feel so guilty for talking to the opposite sex? And in my opinion, the most boring topic to chime in on. It was probably a 5 minute conversation at most but I am dreading it even though I told my boyfriend it happened
