Dealing with Relationship OCD

ever since I’ve gotten into the later months of my relationship my OCD has been on overdrive. i think it’s the uncertain feelings/thoughts I have and they make me uncomfortable and I’m unsure how to deal with them. i love my partner, but I’ve noticed I get harmless “crushes” on others (coworkers, etc) and feel ridiculously guilty if I catch myself feeling that attraction. It’s not out of fear that I’d act on these emotions, but more the question of “what does this mean about me and my relationship” etc etc. I will ruminate for hours and feel the need to tell my partner every time I get these crushes. Has anyone else struggled with this?
