A guy that I use to like disrespected me and was rude so I don’t give him time of day and I see him looking me?

I know he definitely doesn’t like me. I was wondering if he’s trying to break the ice not because he likes me but because of me not giving him the time of day? Also when I walked past him and I wasn’t acknowledging him out of the corner of my eye I had seen he was talking to a female coworker and he looked over at me and smiled. No rude comments please.
