What do I do and why is he obviously still interested in me but won’t say sorry?

How do you deal with a man who hurt you and is trying to get close after you distanced yourself, but he isn’t saying sorry?

He’s a coworker so we have to interact at work occasionally. He says hi when he sees me. I say hi back. Sometimes he offers me help or tries to say a joke. But I don’t get why he can’t say sorry since he clearly still likes me since he’s saying hi. He also will go out his way to look at me too at times.
