Does Anybody Else Struggle With This?

I have been battling ocd for over a year now and it likes to switch themes. Currently, it’s attacking my relationship with my girlfriend who I’ve been with since I was in high school over 10 years ago. It first began as an intense feeling that I have to leave or break up with her over dumb little things. Then it changed into a lot of guilt for having any thought about another girl. And the worse is feeling this intense guilt for past things I’ve done in the past while in this relationship. We were so young and I was teenager, but I often found myself watching porn, fantasizing about real other people in my life, and getting off to other girls that I may have known. When I was younger I didn’t think it was bad and that it was just a normal teen boy thing, but 10 years later I have so much guilt about it. And yes I’m with the same girl now. We’ve had our ups and downs, but I know I love this girl and I’m ready to propose to her soon. Anyway, these past mistakes I did when I was younger make me feel like a cheater and I can’t stop ruminating about it. I feel like I have to admit every detail and person I’ve ever had a bad thought about. I feel like if I propose to her and don’t tell her everything, that I’m a lair and didn’t give her the full picture. And the other day one of the girls I thought was hot when I was younger, came up in convo and I just went downhill. Now she knows I deal with OCD and she is very supportive, I’ve told her before that I did some bad things, but never all the details. And that’s all my brain keeps telling me to do. I have so much tightness in my chest and just want to be able to breathe again. But everyone says to not admit or it’ll reinforce the cycle, I’m just not sure how everyone else does that. And at the same time, maybe I am a cheater and just simply a bad person. Idk! I never cheated physically or anything like that, but my past mistakes feel like I did. But again I may just be a bad person! Please if anyone has advice or is dealing with similar things, I’d appreciate the help!

I have this deep fear I’ll accidentally cheat on my long term partner. This fear was initially triggered a couple years ago after being at a bar with my friends where I enjoyed the attention of being flirted with by a stranger. Because of my enjoyment of receiving verbal attention, I began spiraling about what if I accidentally cheat. Since then I have made multiple confessions to my partner to seek reassurance, replayed events over and over in my head, spent hours googling/looking at reddit threads, and now I dread “bar like” situations where I know my partner won’t be around. Today I was triggered and have wasted about 4-5 hours of my day ruminating. Does anyone else with relationship ocd struggle with this fear and have any tips?

Despite the fact that I have never once acted flirtatiously with someone else over the course of my 3-year relationship, never talked to anyone inappropriately, never touched or interacted with anyone inappropriately, I have been battling constant ROCD obsessions centered around cheating ever since my partner and I got together. I am constantly worried about whether certain things are cheating: daydreaming about another person (already told my partner about this and he said it was okay and that he does it too), talking in a group chat with someone, sitting next to someone, speaking to them in person. I question my intentions. I worry that I cheated by wearing my hair a certain way in an attempt to look more attractive or by jokingly poking someone with a fake sword (despite doing it to other people too), looking through someone’s social media, etc. I have confessed so many ridiculous things to my partner and he’s always told me that none of them are cheating. I feel so guilty for being attracted to someone else, despite the fact that my partner said it was fine and normal. I have made a very very conscious effort to limit my interactions with this person. I never ever ever ever message them privately, I make an obsessive effort to NOT reply to their messages in a group server (constantly keeping track of the ratio of my replies to their messages compared to other people’s), to ignore them when I see them in person and hardly ever speak to them or initiate conversation with them. Yet I still feel like a disgusting dirty cheater who is hiding a big secret.
