Hey! I've been with my partner for just over 2 years, and he's perfect. But I know I have commitment issues stemming from my parents' divorce and other bad relationships etc.
I have relationship OCD (ROCD) where I'm constantly questioning my feelings/attraction for my partner and worrying he's not right for me.
I'll copy and paste some info about ROCD for context:

1. You’re preoccupied with very small details that make you question everything about your relationship.
2. Constantly reading articles that define what a “successful” relationship looks like.
3. Speaking to friends about their relationships and comparing it to yours.
4. Always questioning and thinking about your partner’s qualities.
5. An endless quest for the “perfect” kind of love. This obsession keeps you from actually experiencing it.

I ended things with my partner for a while but we got back together because I realised I truly did love him and want to be with him, but I still have this absolutely debilitating fear that I'm stopping myself from meeting someone better- even though I know there really is no one better for me than my partner.
I know this is totally illogical but I don't know how to help it, it's causing me so much mental distress.
Has anyone else dealt with this? or something similar to this?
