Does this guy at work like me?

I'm not sure if this guy at work is interested in me or not. We follow eachother on instagram and everytime I post something on my story that could start a conversation he responds to my story, and everytime he posts something I write to him. It's like everytime we have an excuse to talk to eachother we do. But when we write it is mostly banter or we tease eachother. Everytime he sees me at work he is always so happy to see me, when I flirt with him he flirts back and he even complimentet me that he liked my scarf one day. I live in another city so I have not worked at this place for now 3 weeks, but him and me have not gone more than 7-8 days without being in contact, but like I said we only contact eachother when one of us puts up an instagram story.
