ERP exercises for Partner focused OCD?

Can anyone relate to this type of ROCD? It’s like i obsess of my partners past, I’ve spent probably 100 hours over the last 3 years asking him about girls he was with before me questioning him about every little detail and seeking reassurance. I don’t want to think about these girls at all. And I’ve been in ERP since August and was doing really good and not sure if it’s just getting bad again the last few days because of the holiday (Easter) and i had to go to his hometown where I know he had a past in and he recently brought a ring which I’m so excited about but it just seems like it’s getting harder for me and i don’t wanna be talking about girls he dated for a few months before me when we are about to get engaged. Am i ruining my future? What can I do to help and to not bring up stuff about the girls before me? How can I be in the moment and not relate everything to an irrelevant girl before me? Help

Been struggling with existential OCD lately. Very hard to describe the thoughts/feelings, but it is a constant feeling of being stuck in my head. Like what is consciousness and where do I think from? Like I think it’s OCD, maybe it is maybe it isn’t. But if it is, what would be good ERP exercises? Just existing (lol)? And what would be my response prevention? I’m not even sure what mental compulsions I may be doing.

I am at a very difficult spot in my relationship. My boyfriend and I have been together for 6 years, and I have a history of cheating that for years we’ve been trying to work through. To me, it makes a lot of sense that my OCD has attached itself to this and for the last few years I’ve experienced intrusive sexual thoughts of others and relationship ocd. I have been open to him about the content of my thoughts and now, with a proper diagnosis of an anxiety disorder, I am able to reframe them and work through them with ERP so that my brain will *hopefully* get bored and stop sending them. But, things have not been easy. As a result of this and everything in our past, he has become anxious about all the scenarios where I could be having sexualized thoughts about other people. To him, if I am thinking something utterly different than what I am telling him or acting like to him, he can’t fully trust it. And of course, I can imagine how difficult it is to know your life partner is sexualizing others in her brain and to be able find a way to dismiss them as unthreatening, especially when past mistakes say otherwise. Is there anyone that has gone through this with a partner? And other than repeatedly explaining the egodystonic nature of my thoughts and providing reassurance, what are some things you did that helped them? Any advice helps! Thank you
