Could this situation still be bothering me because of OCD?

I’ve been struggling with obsessive thoughts about a situation where my girlfriend cried over a past friend-with-benefits going into the military. Even though she’s reassured me multiple times that it wasn’t about him but about the situation, I can’t shake the feeling that it’s bothering me more than it should. I find myself constantly revisiting it and seeking reassurance, even though I know the answers. I’m starting to wonder if this might be connected to OCD, where I can’t let go of the thoughts and feel compelled to keep asking for reassurance. Has anyone experienced something similar, and do you think this could be related to OCD?
