Does my work collegue like me? signs signs signs HELP b4 i make fool myself?

I have been working for about a year now for a large company. The guy who interviewed me and hired me i was instantly attracted to. Just recently he has becomes our Op's manager for our floor and sits in an office close to my section. Our company is very strict on harassment sexual and mental so pretty much everyone is careful not to overstep boundaries. The last few months i have talked more to this guy and really found i like him. He is a decent person and pretty much easy to talk to if your on the same wave legnth. So basically i arrived at work at 7am and he was in his office early and it was only the 2 of us for half hour and i went in and stood chatting to him. I had just got back from OS as had he so we were chattig about travel. During the whole time of convo he looked me in the eyes while we talked as well as turned to face me slightly with his upper body and smiled a heck of a lot and laughed. He seemed happy to keep talking and it was me after half hour who said i better go do some work. A few hours later i went back in to show him some photos on my iphone that i told him i would. When i went in i crouched down next to him on the corner of his desk and started to show him pics in my phone. Ater a few pics he leant over and clenched his hand behind mine holding the phone and brushed it completely accross mine while taking it out of my hand to look at the pics. I remember thinking omg did he just really do that as to me i would think that in his position he would try and avoid touching my hand and grabbing the phone by the top or something so as not to touch me and give me the wrong idea. Such a little thing i know but i just find it weird that he would touch / hold the phone in both our hands for a couple seconds the way he did if he could just pick it up from the top as most would do. I know when i like someone i do things like this to show affection The whole top of half of phone was there to be grabbed and he chose to do what he did? . When it happened he was still leaning quite close to me while looking at pics and laughing and chatting. I asked him if he had been to asia and he said no he was waiting till he had a partner who wanted to travel to asia. I said i thought you had a girlfriend and he laughed and said yeah like 5 months ago when i was livong interstate. So that was yesterday and when i passed him walking to his office today he just did the look up at me raise his eyebrows quite high for a second or so with a very slight smile and eye contact. He has pretty much always done the eyebrow thing since we have talked more. Whenever i have talked to him he is always smiling quite largely and 100% locked in eye contact with me. I get all shy when i walk to my desk as his office is like a runway to my desk so if i look straight ahead i look right at him so i dont look ahead so dont know if hes looking at me or not. I know most work staff dont talk to him but i chat to him at ease like a mate and he reacts likewise. I really have alot chemistry for him and have tried to fight it for so long because of the work thing but after the incident yesterday i seriously dont know what to do. Thoughts?
