<human>: Can you succinctly summarize the text in 1-3 sentences?

We've worked together for over a year now, though we've known each other much longer. I realized last fall that I really liked him. He had a girlfriend at the time, and we work together. So I've just been trying to ignore it. I've dated other people  but I just can't seem to keep him off my mind for very long. 

We get a long so well, and I really enjoy talking to him. Lately, he's been much more flirty with me at work. It seems like he's always in my office for some reason, he texts me after work hours, but it's like he's careful not to cross any lines. So it's hard for me to be certain that he's really interested. Last night I saw his roommate, who's a bartender. I ordered a drink, and he says to me, "So I hear you and [coworker] have a lot of fun at work."  I'm not sure exactly what to make of that. 

The problem is that I'm kind of his boss. It's a small company; there are 2 owners, a general manager, I'm the office administrator, and he's one of 8 technicians. I've been resisting for a while, but I really think he's worth the risk. We don't a policy about employee relationships, but I feel like it would be frowned upon. I honestly believe that there is a lot of potential between us though. 

I guess I just don't what to do from here. I'm afraid to open with him, because I'm not certain of his attraction to me. I'm guessing he's in the same place? I don't know. I mean, I'm his boss so maybe he doesn't feel safe making a move.
<bot>: I have a crush on a coworker. I think he likes me too, but I'm not sure how to proceed.
