I wonder if my coworker is interested in me

So I am a remote employee (F) and I work with another remote employee. We are a few years apart. But there’s an office that we can go to optionally. Sometimes he asks me to come in just to hang out. When we do have the whole team in office for big meetings I catch him looking at me. He’s a social guy so he makes rounds with everyone but eventually comes back to spend time with me.

Recently we had a work happy hour. He sat in close proximity to me and showed me photos of his niece, himself as a baby and his dad. As well as kept running his shoe over mine and didn’t seem to “notice”. Another coworker was eyeing us from the corner because it looked like something was up.

On another work call he randomly said “ oh my friend was telling me this weekend that he actually dated two different girls with your name”. My name is unique so it made me wonder how that even came up - if they were just talking about dating history or he specifically mentioned me and the friend told that story.

We went to a comedy show together once after a work event was canceled and I invited him to a restaurant I liked a separate time. But he has never asked me to hang out without a work event or a work related thing being the reason we see each other first.

I actually don’t even know how I feel about him but I’m trying to gauge what he’s potentially thinking. Maybe just friends. Maybe just attraction. Maybe an actual crush but he’s hesitant to act because we are coworkers. Just looking for thoughts :)
