Am i in the wrong? AITA

I’ve been struggling so hard with mental health issues and poor health at the moment and I really don’t want to be in a relationship right now, I don’t feel ready to be in a committed relationship when I want to focus on getting myself healthier. I do love him but I don’t feel like it’s fair for me to subject him to a relationship where I can’t be fully committed and I would overall just be happier to be single for a while, whilst I figure out what I want fully and where I am with myself.

I keep trying to tell him this but he keeps trying to find a way around it and he isn’t understanding. Am I in the wrong? I feel so guilty because I’m putting myself first and I shouldn’t be, I should be putting him first but I just can’t right now and I don’t want to be in a relationship. Sorry for this being a little bit long.
