Does my coworker like me?

I started this job a few months ago and so did he. We’re the same age and position and went to the same college (didn’t know each other there though). When we first met, he said he remembers seeing me before at a bar because he was actually friends with one of my friends (I have no recollection of this). He’s naturally a friendly and outgoing person, but when he’s taking to me, it just seems different. We sit near each other and he is always asking me questions about my personal life. And when I answer his questions he seems genuinely interested and is like “wow I didn’t know that about you” stuff like that. When he talks to me, he usually makes eye contact for a second and then kinda looks down.

I joined a new team at work last week, and he did a coffee order with his team and messaged me and said “it wasn’t the same without you”. We had a holiday party with the company two months ago. He complimented the bracelet I was wearing, but he didn’t talk to me much at the party. After, a few of us went to a bar. At the bar, he wouldn’t stop talking to me despite us being in a group. He kept asking me more questions about my life and offered to buy me a drink. The day after this, he requested to follow me on Instagram.

This week, he messaged me out of the blue telling me this girl on the team misses me being on the team.
