i need help. how do i live if i don’t know for sure if i did something or not? it’s something i would never ever do. but what if i did and i don’t remember ??? i feel sick and guilty it’s been days

i feel like i have been posting a lot about this and i will try to stop since now but i just don't know where to start or what to do, and i can't take therapy right now either. my event is about something that did actually happen; i had a boyfriend and we had a 1.5 age difference (i know this sounds stupid) but the thing is that we both started to sext a lot since he was 14 and i was 15. we shared audios videos pictures ect and i don't know how to just let this go, even when i know that i never really forced him into anything and i was always constantly worried about him being comfortable, when to stop and ect. the memories keep coming back to my mind and the guilt is eating me up slowly because i keep thinking that i'm a predator or a groomer or something like that. i don't know how to deal with the what ifs either, lately i haven't stopped thinking what if i sexually harassed or sexually exploited him or something like that. how do i deal with the cycle of guilt and constant what ifs if i also feel like my event is worse than others i've seen? please help me with this. it's getting a lil tiring and even if somedays i know how to deal with this, i still get really triggered sometimes. this wouldn't even bother me before, i wish i could just get back in time before this theme popped into my mind. my life has been a hell since then and i live constantly scared and suicidal.

I feel so scared and gross and i keep replaying everything in my head for reassurance but everything feels blurry. I just need exact information, exact proof that I didn’t hurt someone.

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.
