Obsessing over a person, anyone has advice?

I’m at a loss about what to do. I’ve been with my partner for about a year. I’ve wanted to be with him for 3 years and now I finally have him, I got out of a really toxic 11 year relationship about 4 years ago so I’ve had plenty of time to heal, things where going so great at first in our relationship and I’m still very much happy with him, I love him more than anything, but the past 5 6 months I’ve been having a constant fear that he’s gonna cheat or watch 🌽behind my back any chance he gets , I know that’s a touchy subject for some, but me personally it just makes me feel that I’m not attractive enough,or feel like I’m not good enough, I’ve never found evidence of cheating, and I’ve found 🌽 in his history once but I told him how I felt and he told me he understood how I felt and wouldn’t do it again,and I know the constant asking everyday and needing for reassurance with it is putting a tear in our relationship, I just want to fix it. Does anyone have any advice on how to redirect my brain whenever I start overthinking about it when I’m not around him? It just puts so much stress on me when I’m not around him cause I’m just constantly in my head about it.

I stated dating my boyfriend about 3 months ago. This is my first boyfriend ever. He’s been in 2 serious relationships in the past and multiple sexual partners. I’ve had neither. When we first started dating/ at one point were just friends, he told me a lot about the last girl he was in a relationship including their sex life. Fast forward to us dating for about a month and I found out he had been texting her. We almost broke up. But also for context she broke up with him because she figured out she was a lesbian. But still… anyways we moved past it. And now… I’m sure we can all see this coming… I have this theme! I think about his ex gf all the time. I stalk her on social media and try to find hints and clues about their relationship. I compare myself to her. It really impacts my relationship because I’ll get mad at him for no reason. For example we went thrifting recently and he picked out stuff that completely wasn’t my style, but was hers. Which made me spiral. Is he purposely dressing me like her? Does he want me to be someone else, someone like her? The whole texting her thing was put in the past. I’ve forgiven him. But I can’t help but have resentment towards him and think/ visualize all these thoughts about them together and how I’ll never measure up to that. It makes me think I shouldn’t have got into a relationship. That maybe I’m better off by myself. But like all of us. I wish I didn’t have these thoughts. I wish I could believe he liked me for me. But sometimes it’s really hard.

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..
