What exactly does self-reassurance look like and is it something to avoid?

When I feel anxious about my relationship with my partner, I often think to myself "I love him" even when I'm scared i don't, just to remind myself of the truth. Is this self-reassurance?
I tend to feel better afterwards, but should I try NOT to think that?

Relationship OCD

Sexual Orientation OCD

From what I’ve learned so far, yes you should try not to do that and try to shut down the thought. My therapist taught me self reassurance is a compulsion. Trust me I do it all the time and I’m learning how to stop too. 

What you should do instead is think about how you can’t think those thoughts right now, because you have to focus on XXX instead, and move on
