He isn’t my boyfriend but is very possessive of me and my body? Is it possessiveness or controlling?

The guy isn’t my boyfriend and has said he has no romantic interest but I catch him looking at me all the time.
I was the only girl he chased for years. But I left him because I was afraid of attachment and his feelings were strong. Although he denied liking me Once in an argument he said “you made me chase you. I was never after any girl this long but you made me run after you”.

Somewhere I feel he likes me but is scared of attachment as I have once left him.

But he is way too uncomfortable if any guy talks to me at night or touch me. That makes him mad.

He isn’t my boyfriend but is very possessive of me and my body? Is it possessiveness or controlling?
