HELP PLS I NEED ADVICE

I’ve been struggling with relationship OCD and differentiating between what is an intrusive thought and what is a real doubt. I was really happy with my partner then I got one aggressive thought that I didn’t love him and this spiralled into noticing all his flaws. I struggle being around him because I feel a huge sense of guilt that these thoughts even come into my head and I cannot figure out if this is my brain lying to me or this is how I feel. It’s really impacting a relationship that is so important to me.

i feel so bad for posting here, idk what i wamt i have so many thoughts abt the feelings i have for my bf im scared my thughts are true or that they will be true and i feel bad for feeling amd thinking this way i such a bad girlfriend, i am scared that i like other people just because i look at them or talk to them normally and i feel like a liar what cam i do to stop feeling like this i am scared

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?
