<human>: Can you condense the text into a few key points?

I have a huge crush on a co-worker - he's one of the most attractive people ive seen before, ive even had dreams about him. we've hardly talked and his behavior seems either really shy or intimidated by me, or totally uninterested. He will do little things, like comment about my "boyfriend" to gage if I'm single, grab my hand to look at my tattoo, get really quiet around me when he acts pretty normal around everyone else. When we make eye contact his eyes dart away quickly, unless im across the store then he will look sometimes.
I don't want to be direct and ask him out, since i work with him so if i'm rejected my workplace would be ruined. What the hell can I do? Every night I work with him and leave I feel so frustrated because I just want him to make a move or I wanna get to know him better. My behavior is also pretty shy around him, too, so i don't think he knows for sure im interested. Should I just be super flirty for one shift and see what he does? I hardly know him and it's driving me crazy..
<bot>: I'm really confused if my crush is interested and want to know what little things i can do to show him i'm sorta into him and give him a push to ask me out
