there's this guy I just met at work for maybe 3 weeks (seen him around before though). He was briefy moved to my direct work space and has been friendly (would speak). While there for one week he'd place his hand on my arm to speak.... Then he place his hand on my back the next week ( and talked for a bit). The next week he put his arm around my shoulder as I met him (by incident) walking down the hall... And says " I was just coming to see you". I know he likes me but is he doing too much too soon.. Today he comes up to my desk (he's back working downstairs) and hugs me akwardly while i'm sitting in my chair, putting his head on my "chest". I tried to push him off because it shocked me .... Am i over reacting, what does this seem like that he's"only" interested in something physical.. I did initally like him but now i'm just weary of what type of person he may be....
