Guy's Behavior

Flirting and subtle body language meaning?

I like this guy at work. I can’t tell whether he likes me back or not; however, the other day this one girl who he’s known for years asked if I had a crush on him. I said no (it’s work. I don’t need the drama of other people getting involved) but her response was “well, from what I can see, you two have chemistry. You two share a bond that is hard to find and I wouldn’t just let that go. It’s just something to think about.” I don’t know if he said something to make her say that or if she just observed us interacting…. But from my standpoint, he’s a little stand offish. Our flirting is all in the eyes. Sometimes verbally but never that cute touchy feely type (which I’m used to). We’ve made physical contact before (insignificantly) and here’s what I don’t get - we touched hands by accident and he immediately pulled away. I touched his leg and his bicep and he let me. On another occasion we were laughing and I bumped into him and he put his arms inwards as if he didn’t want me touching him. But when we’re standing together, walking, or sitting next to each other, we are inches away. I don’t get it. Why is he so quick to pull away yet always in my personal space? Also, some days he’s ALWAYS around me and we will have a blast and laugh and talk. Other days, he gets all weird and will maybe say hi once and that’s it for the entire shift. I don't know why he’s so wishy washy with me?
