What is it with men who get in a relationship and always come back in contact with the one who didn't want to be with him?

He said she was good in bed and wanted a relationship with her but she wanted to take everything slow.
He didn't want to wait and saw it as "she doesn't know what she wants" while she knew he cheats in every relationship and hoped that he would change but luckily she found out that he didn't change, so she said she had other plans for her future, and yet he still contacts her to try to get her in bed.
She still doesn't want anything to do with him, for her it's over and she won't meet him again.

Why won't he give up? While she keeps saying no and she won't take action to meet him.
As if he is addicted to her and he hopes that she sees pass all that?
