Please I'm very sad (about daydreaming)

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?

I guess you can say I’ve been maladaptive day dreaming. I never had a good childhood I would go to sleep and pray I never woke up around the age up 10 I found daydreaming as a way to cope with the trauma and I’ve been daydreaming since, I still do it now. I always think im gonna meet the love of my life and they would love me for me and accept my ocd and make me feel beautiful and I’ll be rich ( I didn’t grow up with money). But then I would have to come to a realization that I’m not getting better, I’m still insecure with trauma. No friends or family to know what I’m going through and it’s hard wanting a reality you can’t have.

So, yesterday while I was laying in bed, I was relaxing when suddenly I had an intrusive thought about someone, but the thing is that it brought me a sense of enjoyment or calmness for a few seconds before it went away. Once it did, it was only until hours later when I realized what had happened and I began to freak out because I'm reading everywhere that when someone experiences this type of thing, the anxiety happens shortly after the enjoyment or "false" enjoyment. Can OCD do this?
