Losing attraction and obsessing over flaws

I should start by saying I have never been diagnosed with OCD or any mental disorder, but I’ve been researching ROCD per my girlfriend’s suggestion on and off for 6+ months now, and all of the symptoms and descriptions have hit home for me. However, I worry that I’m using ROCD as an excuse for continuously convincing myself she’s enough for me. The core of my fears is finding others attractive, and more attractive, than her — when I see a cute girl, or someone with features I naturally desire, my ruminations/episodes begin. After that it doesn’t take long to lead to doubting the validity of the entire relationship, and whether I even love her at all or want to be with her. It doesn’t help that we go to a university, so I’m inevitably surrounded by attractive people constantly. My main fear is that I’m settling for her appearance, even though I’m attracted to her and, truth is, I think she is hotter than me. And I feel like I tell myself that the only thing wrong with her is her appearance, because she is everything I want otherwise (personality, compatibility), but she’s just not my physical type. Every time that these fears and doubts build up from rumination, we talk about it. The end factor is that it almost always ends up being a result of intrusive thoughts. In fact, the last time we talked about this (about two weeks ago), we had makeup sex and I had an intrusive thought of a particular girl that’s in one of my classes. I did everything I could to purge this thought so I could enjoy the moment, and eventually it subsided — but I found myself “checking” by opening my eyes and staring at her throughout for reassurance that it’s her I want. I then told her about it right afterwards because of the massive guilt I felt, and she was a bit less understanding (rightfully..). We’re now at a breaking point, where she loves me and I’m pretty sure I love her, but I’m still having these doubts and I don’t know what to do to deal with them. I am convincing myself that they are significant and important because of their consistency now that it has been 8 months of us dating. I have told her I need time to think about this and figure out what I want, and I know this is destroying her, so I need to decide to break up or not now, because I can’t stand knowing she’s going through this. At what point am I just fighting this “gut feeling” because I know I’m settling, or is it just ROCD lying to me because she is so important to me?

Do you have any ideas/inspiration for exposures on partner-focused ROCD? I struggle with my partners physical flaws, it's very distressing for me even though I find it ridiculous that a simple thing like hair or face shape can cause me so much irritation. Furthermore I sometimes have problems with my partners behaviour, like making a lot of jokes or behing a bit hyperactive (this is mainly the case when I don't feel good/feel tired etc). I stopped confessing to people how I feel about his flaws. My main ritual is to constantly look at or think about the things that are bothering me and check my feeling. I ask myself If that means we are not compatible or if I don't find him attractive (enough), at the same time I have a lot of shame. I really want to work on this because I don't want this to destroy the wonderful thing I have. So I think I need to start doing the work. I'll also see him this Friday for the first time in over a month (due to ldr) and I'm a bit nervous how things will go. Any advice?

Had for ocd for years about loyalty towards my gf would feel awful if I thought bad off my gf and thinking other girls r goood looking missing my ex ect but now I’m almost better and now don’t avoid looking at girls which I did for a year I find my self wanting to look at girls and get an overwhelming attraction feeling that I don’t get towards my gf? I find every girl attractive now and feel awful like I’m better off alone as I feel Numb a lot towards my gf but thY would be because of all the trauma towards her from ocd. Any one else struggling with this ? We have been together almost 24/7 for 2 years is this normal the lack of attraction ?
