Retroactive jealousy

Anyone struggle with this with having ocd?

For the past 3 months ish I’ve been struggling on and off with this anxiety and fixation over my relationship. To wondering if i still have feelings for an old friend, wondering if i actually love him, wondering if the thoughts are all real and im just trying to cover it up with ocd. It sucks, when im talking to my boyfriend i feel fine. The words i love you and talks about the future come naturally. I can’t imagine myself with anyone but him. But this constant rumination on my relationship is KILLING me and I’m scared it’s going to ruin what i have. It makes me numb and disconnected which therefore makes me believe the thoughts even more. They just feel so real sometimes and it’s so scary like why can i not just enjoy it. We’ve been together for a while so i know there’s periods of like feelings ebb and flowing but this is so much more. It’s just constantly sitting on my chest with anxiety. My compulsions are coming on this app, looking at photos of us and confessing it to him. He’s very understanding and helpful. I love him so much. I just need help / I’m also just starting new meds as well ..

I’ve been struggling with something that’s been really overwhelming, and I’m hoping to get some perspective from others here. I feel a lot of guilt about it, and I’m not sure if I’m alone in this experience. Lately, I’ve found myself daydreaming about romantic situations or getting caught up in ‘what if’ scenarios—where I wonder if I could develop feelings for someone else, or if someone develops feelings for me. The thing is, I’m in a relationship that I love, and I don’t want to act on these thoughts at all. What makes it even harder is that these thoughts often hyperfixate on one specific friend, and sometimes they feel entertaining or give me a dopamine rush. But then, of course, I feel even more guilty because it makes me feel like I’m betraying my boyfriend. These thoughts usually happen when I’m upset and looking for comfort, but then they morph into romantic scenarios, which makes me feel so disloyal. I’m constantly going back and forth between feeling curious or entertained by the thoughts and then feeling horrible for even allowing them to happen in the first place. I keep confessing these thoughts to my boyfriend, and he tries to be understanding. He’s just never been the type to daydream, so he doesn’t know if this is something other people experience or if it’s just me. I feel like such an awful girlfriend. Has anyone else dealt with something like this?
