tik tok and ocd

I’ve just recently found out that Relationship OCD is a thing. I feel like I relate but it also feels like relationship trauma. I’m in a fairly new relationship and I keep telling myself that things are going great, we are good, he cares for me, but does he? There’s this unbelievable amount of self doubt that sits in me because of what my ex did to me many months ago. I kept getting told that I do too much, i smother, need constant reassurance, then got told that I don’t care enough, the things I do aren’t enough and that I’m not enough. I feel like I am waiting for the day that I get broken up with because of these “problems” just so I can be proven right at the fact that I should be considered unlovable. I go through this every month around my period because I get so emotional and nervous that I stress over the idea that he doesn’t like me. How does someone continue a relationship with Relationship OCD? How do I explain it?

so i was on instagram and it came up with other signs of ocd then someone commented this doesn’t mean you have ocd now im stressed that its not ocd background - i had so-ocd for a few years then got treatment for it but am now on the waiting list for further treatment for other stuff but i dont have another theme which makes me feel like its not ocd my day to day life consists of touching the door handle every time you go past it or someone will die, and inability to send emails without re reading loads of times and getting other people to check because im scared i wrote something bad but the what if it’s not ocd thought is triggering me now and i don’t know what do

i’ve been dealing with this “thing” since i was 15. (i’m 23 now) if i have a bad memory that i have done when i was really young or just an intrusive thought i feel like i need to tell my mom or boyfriend. it’s been on and off ever since but since January hit it’s been an everyday thing about the littlest things. mostly about my relationship. an example is i was talking to someone random at my job and we were talking about taxes and when im in deep thought or just thinking i do a thing where i bite my lip (not in the sexual way) and i had a thought when it happened “was that sexual?” and i felt like i did something wrong and i went for a while thinking that until i told my boyfriend about it. or like my ex’s face has popped up in my head in the most inappropriate times and i feel the need that i have to tell him. (my ex was not a good person) i feel like im a prisoner in my head everyday, trying to justify thoughts or remind myself that its just a thought. i didnt know that this was or could be a form of ocd. it runs in my family but i’ve just never considered it being this. i always called it anxiety or depression but i always felt like it is more than that.
