How do I help this guy I like to ease his fears of commitment?

It turns out after a year of mixed messages that he likes me but he’s scared of losing his independence if he ends up dating me. I’m slightly needy from abandonment issues, but I am not possessive or jealous. I like my own space, too.

This is an entirely new situation for me. I’m autistic and I could do with some guidance, as I lack the instincts of knowing how to respond.
