I just learned about a different form of OCD called Relationship OCD. There's a Youtuber called Special books by special kids who interviews kids and adults who have disabilities. The woman he interviewed had Relationship OCD, she would constantly worry about if her boyfriend truly loved her and would always question if her actions caused him to not like her. I never knew about Relationship OCD, but I can imagine it's got to be extremely exhausting to deal with. Her and her past boyfriend didn't work out, but she's been going to therapy to help her cope with Relationship OCD. Here's the video I watched if you're interested:
