Why doesn't he delete my number?

Anonymous
He ghosted me after 2 dates but I still kept things civil and continued greeting him whenever we saw each other in public as we study at the same uni..
He , however has always looked really bitter when I stopped texting him 3 months ago. He would also make stupid comments which further showed his bitterness.
I never texted him regardless and he despite all his bitterness, I ve caught him numerous times looking over at me in a sneaky way. He tries to hide it when he looks at me and still checks me out.

He wasn't well so I sent him a text saying just wanted to check up on him and stay safe take care but he never replied.
But like I said, he doesn't delete my number (I know this because his last seen on Whatsapp is set to my contacts only) and still stares at me.

When he doesn't want a relationship more wants to talk, why do this? Is he insane?
