Does anyone every worry about their significant other cheating on them with Rocd?

Does Rocd make it nearly impossible to forgive your partner for anything. Whether it is big or small? My situation is so gray area where there’s something my bf did that I feel like I’m not okay with but he did this when we were first dating (not bf and gf yet). I ruminate all day about it bc I don’t want to lose him and see a future with him and I know he loves me so purely. But I also feel like I’m going against my morals here bc I do feel betrayed by what he did. I try to forgive him by diminishing my feelings and telling myself “he never did anything physical with a girl or went out with another girl while we were together” but still feel so hurt that he even messaged another girl while us dating. He’s given me an explanation and has proved how much I can trust him so I’m just completely stuck on whether I should forgive something I know I would’ve never done to him or leave him even though the only thing he’s done wrong was before us becoming official. I’ve broken up with him countless times over this situation bc I feel like I “can’t live with it” but then immediately when we break up I want him back and I kind of understand his explanation and reasoning. I don’t know what is ocd and what is my real intuition anymore. I genuinely think it’s both. Are any of you guys in the same boat?

I'm 18, and been in a relationship with my man for nearly 2 years. I started living with him around 2 months ago, and all I do is think about if he's cheating. We were long distance for a year and a half of our relationship, maybe seeing eachother once every month or two. I decided to move in with him, and ever since all I can think about is if he's cheating or watching porn. When he's in another room I think he's doing something wrong, I have to check on him every ten minutes to ease my anxiety. I didn't have this problem before moving in. Granted he has talked to some girls on his phone, even having his ex on his phone (didn't do anything bad) and he is porn addicted though he is getting better for me. It's gotten so bad I want to leave him. A couple days ago I broke up with him and it absolutely broke my heart, I couldn't bare it so I gave him a month to show me he can do better, and for me to work on myself. If I'm still unhappy with us I'm going to leave. I love this boy more than anything. I'm scared to be without him, this is my first real relationship. At this point I refuse to even sleep until he is sleeping. I don't want to start over, I don't want to leave him, but I really can't take this pain it's causing me. It's all I think about. I've convinced myself so many times that he's cheating, but I know he wouldn't. I question whether it's anxiety or intuition. Maybe I just know deep down he really is cheating and I just don't want to believe it. I don't know. I don't think he would do that, but at the same time he's really into women. I hate that he looks at other girls in a sexual way, it bothers me so much, and we talk about it often, but with it being an addiction it's difficult. He has gotten a lot better since we have talked about it. He understands I have an issue and is usually happy to talk about it over and over and promise me over and over that he's not cheating. He allows me to have his phone whenever I want and everything, I have no reason to think he's cheating, but I can't get over it. It's not fair to him either. How do I deal with this? How do I stop hurting so much?

Currently I have several different OCD fears that pop up throughout the week depending on the situation. I've noticed a commonality between all of them are the fears relating to memory/false memory. Today is the ROCD struggle I've been dealing with. I know OCD has been trying this on me lately because of how much I love my spouse. They are my absolute best friend and she's my world. I value our marriage and friendship more than anything. OCD has latched onto one specific female coworker. And I don't even know why because even if I were single I wouldn't be into her. Even still, OCD makes me think I've cheated on my wife every time I'm alone with this coworker at work. Always starts as a what if, followed by imagery, followed by feelings that I must've actually done something and can't remember it. Usually fearing I've kissed her. It hurts because I know I'd never do that to my wife and I love her so much...the idea of losing her kills me, especially if it were the result of something I did. Just wanted to vent.
