What’s wrong with me

A friend told me look up rocd because I’m always paranoid in relationships. In a way that isn’t normal — I’m constantly on edge, I never fully trust someone and it takes me ages to even fall in love.

I thought I was an avoidant for the longest time but suddenly it’s been changing. I haven’t dated anyone in a few years because the last person I did said “I was incapable of loving someone.” But recently, with someone I’m talking to, I’ve been obsessed with every move they make. Is this normal? I’m just very confused, and I want this one to work.
