How to get over one particular obsession?

I’m having a big OCD relapse and would like to hear anyone’s tips on how to be present and healthily deal with these intrusive thoughts and the “need” to preform compulsions. Thank you!!

I'm struggling really hard with relationship obsessions. Do I really love my partner? How can I know? Am I really just faking it? That kind of thing. It's making my life and relationship a lot harder than they need to be. I could use a few helpful coping mechanisms, trying to move away from less helpful ones like chasing reassurance.

Looking for inspiration
