I don't want to confess but how?

I’m a good man and I know that. My OCD revolves around relationships. While dating someone a truly enjoy, I find myself needing to compulse everything on my mind or else I feel like I’m being a liar or keeping secrets. I also am pretty confident I suffer from false memory ocd. I don’t like to put a label on things but I’m 99.9% sure I do. My compulsions a lot of times come from things I’m not even sure are real. The more thought I put into them, the more I start to believe they are real. One of the worst compulsions I had in my relationship was I had a thought “what if I find my ex more attractive” and “what if I thought the sex with them was better”. I ended up compulsing these things to my gf. After lots of time to think and get a ahold of myself I was able to remind myself that these things weren’t true and I was just in a downward spiral. There was a 2-3 month period where every time I was relieved of something then I would instantly think of something else. These compulsions have caused insecurity in my gf and I feel like a terrible person. Never meant to hurt her at all and was just trying to find a sense of relief. While I know it is not true, I can’t fix things with words and I feel terrible. I would love to hear from people with tricks and strategies that can help. I love my gf and want to fix things and understand this is not a relationship fixer app but I would like to know what are some ways you are able to deal with these kind of things.

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 suffer with a constant worry of what if I’ve cheated. You name it I’ve thought I’ve done it. I’m quite flirty at nature and also insecure. Sometimes hand in hand I don’t think they balance each other out as the constant need for attention to validate myself can backfire. Although I have the best partner ever and she makes me feel nothing less than beautiful I still crave validation from others. That being said someone I used to work with left over half a year ago and when they worked at my current place of work we were very close. Text everyday, phone calls you name it. However looking back I was extra flirty as I wanted him to fancy me. I wanted the power to turn him down to make myself feel better. Awful I know. Now all I can think about is what if I’ve done something. What if I kissed him. What if I’ve slept with him etc. I’ve kept our whole conversations from the minute I got his personal number. I constantly search key words to see if my intrusive thoughts are real. I can except the uncertainty my therapist tells me about as if I have done the worst and cheated I would loose my partner and our 10 year relationship. I love her so much she is my life but I can’t stop thinking what if I’ve cheated. Does anyone else suffer with the same theme? If so how do you cope?
