If a guys is not usually shy when he likes a girl, does this mean he doesn't like me?

I met a guy in my club who I thought had a mutual attraction from the start, but he ended up asking my friend out who lead him on. Later in the year we started chatting on line and somehow it got ual...he talked too about how he wanted a g/f, but I was afraid he just wanted me as a g/f for , so told him I wasn't looking to date at the time...also, he never seemed interested enough in ME, like not asking those "deep, probing questions" people say guys ask if they like you, so I ume he doesn't. Yet, now we living in the same house and he had a g/f, but they recently broke up cuz she didn't spend enough time with him and I'm knowing him better---he actually seems sweet and decent...Now I see him always staring at me and when talking in a group he mostly looks at me and he's much nicer and whenever he makes a joke he looks right away at me, since i usually laugh...i'm not sure, but could these be signs of something or wishful thinking lol ???? How can i show him i want to date now.
