What is this man trying to do?

My coworker is a married man. But I feel like he is jealous of me. I was talking to another man on the phone the other day. After he heard, he started acting angry towards me. He was drawing a project next to me. He asked me angrily if I could put the phone down and look at the project. He also tries to touch me from time to time. What is this man trying to do? Why is he acting like this when he is married? What should I do?
