Can anybody relate?

Me and this girl have been talking at university for almost 2 months and it’s starting to get serious. We see each other almost everyday and at first she was the most beautiful and cool girl I’ve ever met in my lifetime. Now my ROCD is sparking and making me not want to see her or question if I should continue things out. I think about these things all day, though when I am with her everything is okay. In the beginning it wasn’t present and then one night it hit me. ROCD affected my previous relationship and ruined it and it’s making me fear I won’t be able to positively advance and move forward in this one.
