Why no matter how much I push this man away for doing me wrong why does he not leave me alone?

i left him alone for months , weeks just for him to go be where he wanted to and i can change my number everything he just doesn't stop we not even in a relationship we mutally just beeb around each other for 2 years and he never changes n im over it he doesn't get the point. i know he cares for me and likes me a lot but i wish he understands i respect myself more.
