Does he like me , sexually attracted or both?

He’s a Coworker I worked close with for a few months but no longer work with. When we worked together we joked a lot laughed had a good report. A lot of banter and teasing. Over time I developed a crush on him. When he sees me at break across the room he’ll look at me and I’ll look back and we’ll both just hold that gaze for a few seconds. Maybe 6 seconds or so. No expressions. Something likes he’ll do something silly very subtle tho. Everytime I walk by him he also looks at my ass ( I happen to have A very nice ass). Is he just hardwired to look at me bc I’m physically attractive as an instinct or does he like me / have a crush on me? And is his making eye contact with me a way of him flirting or communicating something. Or he’s just looking at me to look at me?
