Relationship and confession ocd

okay so, i had this friend i met in the 8th grade when i was 13 when we became friends and my nickname for her was “red” and i had a crush on this friend before we became friends and once we became friends the crush faded away and i just grew a close platonic friendship with her and no longer has any crush or attraction or romantic interest in her. then i got a girlfriend named lisa in the 8th grade also and we were all friends and hung out but that summer going into highschool lisa broke up with me, we dated only for 2 months so you know it wasnt a big deal. and my friend “red” she and my other friend lana we are a trio and they helped me move on from that. then i started 9th grade (my freshman year of highschool) and i went into this year thinking i was gonna stay best friends with this trio but we ended up splitting paths but me and my friend “red” always had a more special bond in the trio we were like the duo because we trauma bonded and dealt with mental health problems. and in the end of my first semester i fell in love with this girl named riley (who became my 3 year serious relationship) and i love this girl so much i met her when i was 15 and she was 14, me and riley (who is my current partner) were very toxic during freshman sophomore and junior year. she was very insecure over my ex from the 8th grade who i didnt care about because she was my first girlfriend. and she was also very insecure over my friend “red” because she was my best friend during the time i was with my ex and she reminds her of my ex for some reason. i still wanted to be friends with “red” at the time and we would get into numerous fights about that. she would control me and who i was friends with and said i couldnt be friends with her and i felt so awful and defeated bc i had a close bond with this friend. she then gave me an ultimatum of either her or my former best friend and i chose my partner obviously but she was so in her head i think that she still broke up with me for like 3 days and that day she broke up with me i had to go home with her since she was my ride home and i was broken and she was obviously angry and i was crying while we were walking out of school and then she stormed off without me all upset and my other guy friend and his girlfriend saw me and went up to me to comfort me and asked what was wrong and i told them she broke up with me and then my partner yells my name very upset from across the street comes back and grabs my arm aggressively and drags me past everyone very aggressively and angry while telling me to stop crying because her mom is going to be upset and ask questions and i felt so bad. we got into the car and i had to try my best not to cry and my partner who was visibly upset a few seconds ago just completely smiled at her mom and asked how her day was with such a happy tone of voice and i was completely in shock. hours later since we were broken up i texted my former friend “red” (the one who my partner broke up with me over) and told her i needed emotional support that reyna had dumped me and i needed a friend. and she came over and talked to me. that was all nothing romantic. and then 2 days later my partner says we are back together and i was happy but felt guilty because i hung out with my friend who she dumped me over. Now years later im still with this partner after many splits but we are finally healthy and healing and shes been super supportive and there for me and loving during my recent journey discovering my ocd. i have been confessing over and over many past mistakes or things i thought were mistakes. i last confessed something on monday and ive been feeling better and relieved after confessing up until yesterday when i remembered a past mistake (which was what i just shared) and now i cant stop ruminating on it and feeling guilty and feel the need to confess this to my partner but i learned that confessing is my ocd compulsion and if i give into it ill be feeding my ocd and not breaking the cycle. but im also feeling conflicted on if i should genuinely let her know and confess because i feel what i did that time was wrong but i dont want to give into my ocd but also what if i basically cheated on my partner by doing that and if i tell her that i did what i did even tho i didnt cheat but i told her i never liked this person even tho i had a crush on the former friend and tried to get my partner to let me keep this friendship because its not like i like her romantically which is true i dont but i used to. so i feel like i betrayed her even especially by hanging out with her so now i dont know if i should tell her or if its my ocd and i dont have to share absolutely everything especially if its in the past. i dont want to lose my partner and im scared if i keep confessing it will ruin our relationship and drive her away but it will also make me lose myself and my own privacy and also feed my ocd and compulsions but im scared if i dont confess ill never stop thinking about it and i will feel like im lying to my partner and like i cheated and i wont be able to enjoy the good moments and the present because im stuck on my past “mistakes” and now im scared ill have the end my relationship to feel better but that will hurt me more but im scared if i stay im just going to try to avoid my partner in fear ill confess or feel the urge to confess every time we speak. i dont know what to do im completely lost this is the hardest thing ive ever dealt with and i have a lot ive dealt with in my life already. im barely 17 i havent had a year of a break

I can't stop confessing! I have this urge to dump on him every thought and wrong doing I've ever had and its destroying me! Im worried it'll destroy us too. When we started dating I stole a story from a friend to make myself look cool which was pathetic. But its the only time I remember doing anything like this.

So I have been struggling with the same theme of ocd for 4 months now. My ocd centers around past events/false memories that ocd skews to make seem bad or it twists my thoughts on what my intentions were. this is related to cheating or being weird while I have been in my amazing relationship. I have never cheated on my partner and never will and I believe it is wrong. But my ocd is telling me other wise. I love my partner so very much and I would never want to hurt him but my brain is getting to me. I was getting better. I was trying “maybe I did, maybe I didn’t”, I have been back on meds and in therapy and I stopped confessing random interactions from years/months ago about 1.5 weeks ago and it really helped. But now I woke up this morning and feel the pit in my stomach again. I feel extra critical and like why would you do this? What does this say about you? What was your intention with this? And I’m just stuck mentally reviewing and ruminating on everything you could imagine. I know my personality and I know in the moment maybe I did find them attractive but mainly I was just being nice or funny or even just a good friend, but looking back now I’m like “was it flirting?” “Why did I still snap this person” “why would I even talk to them” and stuff like that. I feel this intense sense of guilt. I have told my partner everything that I keep getting stuck on and he didn’t care, he said he understands or “that’s a little weird but it’s okay” and hasn’t missed a beat. He said eveything I’ve told him is normal and I’ve heard that from my friends too. I just really need help. I don’t know what to do anymore. I am so disappointed because I thought I was gonna be done with this, so why am I still so worried and caught up in this.
