ROCD is about to ruin a friendship

My best friend hasn’t spoken to me in months. It triggered some symptoms that I now realize fall along the lines of ROCD. It’s making me behave in a way that chased my other friends away. I’m feeling very hopeless and guilty.

Ocd sucks. I’m at a stay away multiple days long event for school rn and ran into someone I used to talk with. We had a will they won’t they kind of thing for years and knew each other all growing up. I knew when we were really young that he had a crush on me for a while. And then when we got older there were times I had a crush on him but I don’t think he liked me anymore at that point. I never fully knew where he stood because he often was in a relationship or living somewhere else. Because we never dated or kissed or anything, only hung out on ambiguous date-like occasions, there has always been that what if sitting there for me and I hadn’t seen or spoken to him since before I met my current partner years ago. Well they happen to be at this place I’m staying at, where we are in the same places everyday, and I ran into them, said hi and caught up for a bit. It has totally triggered my ROCD in a way I’ve never experienced. I feel guilt and shame and keep having intrusive thoughts that are so extreme and catastrophic like what if I leave my partner of 8 years for him, what if I find him more attractive than my partner, what if I cross a line while I’m interacting with him this week, what if I’m a terrible girlfriend to my partner and a fraud??

Hey, I really need your opinion – I think I might be struggling with Relationship OCD, and these thoughts are driving me crazy. I’ve been officially diagnosed with OCD, and I believe I also have ROCD. My obsessive thoughts often focus on one specific girl from my boyfriend’s past. She had messaged him a few times, and I think she liked him – but he never liked her back. He barely knew her, never found her attractive, and never wanted anything with her. She’s just a good friend of his best friend – not an ex or anything like that. He told me that he happened to be in the same group as her a couple of times – once at a birthday party and once at a fair – just because his best friend brought her along. He made it clear several times that she’s not his type at all, neither in looks nor in personality. He described her as someone who likes to go out and party a lot, and said that’s just not what he’s into. He also said he didn’t ask about her – these things were mentioned to him before our relationship. Almost all of this happened before we met – except for one thing: the fair. That was just one day before our second date, back when we had just started getting to know each other. She was with his friend group that night. He said he only said hi and bye to her, nothing more. The next day, when we met again, we were talking about his friends’ heights. He casually mentioned that his friend was the same height as that girl – 1.70 m. Ever since, I keep wondering: If she meant nothing to him, why did he even talk about her? Or did he actually talk to her that night, even though he said he didn’t? I know he said they barely exchanged a word, but somehow he still knew that detail. I just find that strange. Another example: He once said she was “kind of slutty.” Then, one or two months later, when I brought it up again, he said he didn’t know if she was or not, and that he didn’t care at all. That really confused me. I keep wondering: Why did he say something like that in the first place if he supposedly doesn’t care about her? I also notice this really frustrating cycle: When I talk to him about something that doesn’t make sense to me, I feel brief relief. But then, almost immediately, another thought or detail pops up that feels “off” again – and I feel like I have to bring that up, too. I can’t tolerate the uncertainty. It’s like an endless loop. These little “inconsistencies” – or what I perceive as inconsistencies – make me spiral, even though I do believe he’s being honest with me. I want to trust him. But I have this constant urge to bring up every little thing that doesn’t feel logically right. Every detail stays in my head for days, and it’s really hard not to talk about it. Does this sound like Relationship OCD to you? Do any of you go through this constant analyzing and doubt? I’d really appreciate your thoughts. I’m slowly ruining my own relationship..
