Does my coworker fancy me?

I started a job 7 weeks ago and I work closely with a guy. I’m 28 and he’s 43. We are both married. He always gives me special treatment (makes me a coffee for when I get in the office for example) and I catch him looking at me when I’m across the office from him. He also said ‘I am quite happy being submissive’ after I joked that I am in charge. He plays my favourite radio station at work. Also his wife looks similar to me. Obviously not ever going to act on anything but do you think he might fancy me?
