Damn I hate this OCD. Every day I wake up feeling guilty like I've cheated on my wife even though I never have. This guilt is ruining my whole existence.

I’m currently struggling with guilt from checking OCD. By this I mean, I feel guilty and shameful by my OCD checking because I feel as that was immoral and wrong and I really don’t know what to do. How can I fight this?

I have false memory real event ocd, I’ve been married 13 years and I used to constantly bring up past mistakes from when we were dating and it RUINED our marriage, but I got medication and therapy and things got better untill a few weeks ago where everything crumbled. I have a memory that is 13 years ago of me being intimate with my husband (than boyfriend) while being intimate I have a memory of sending a text to a male who obviously liked me but I didi not while my husband was under the covers . And I keep thinking over and over how disgusting and inappropriate it was to do that especially doing it in the middle of being intimate 😞. I have confessed this to my husband last year and he didint believe me saying it’s probably a made up memory and would are not a slut and wouldn’t do that. Now i have guilt all over again for weeks and it’s taking such a toll on me it’s all I think about and try to remember every detail I’ve thought about it so much I don’t even know if it’s 100 percent true. But I can vividly see it when I close my eyes. How do I get over this guilt without confessing? Confessing would absolutely destroy my husband.

I can’t help but feel so anxious because of guilt. I feel guilty about not sharing everything about my OCD to my partner, but because I understand that confession itself is a compulsion and would not help anyone. I feel so anxious too that if all my fears come true and she finds out, then it would be so devastating for everyone especially her. Does anyone feel the same thing? How could I change my perspective on this?
