Guy's Behavior

Guys, Could this guy be straight and have feelings for me?

Ok guys, I know the way to get the best answer is to ask him directly but I think I’m too embarrassed or worried that I might be wrong. This guy I work with has been flirting with me for months (the usual signs, like staring, teasing, etc). We have even gone out a few times together alone for drinks. But nothing ever happened. A few of my colleagues have said he’s gay. That’s why I kinda gave up on him. Anyway, a few days ago I was at our Christmas work dinner and was talking to a male colleague. Then he literally shouts my name across the bar and was like come here. I asked why and he said come here, to give me a hug. Again I asked him why and he said because I miss you. That whole dinner he was flirting with me and my colleague said he was watching me all night. Again yesterday when I came into the office he said we missed you this morning in the office. I said you mean YOU missed me. He didn’t anything in response to that. I caught him staring at me several times this week. Today we said goodbye before leaving for the Christmas holiday and it was just a quick hug and see you after New Years, nothing else. It did cross my mind that he could indeed be gay but then why act like this? What doesn’t he just come clean about how he feels about me? SO CONFUSED!
