Does my guy friend like me?

Okay, so me and this guy, lets call him ‘Bob’ have been friends for quite a while and Ive always kinda liked him.

Hes had a few girlfriends and I kinda just was jealous quietly in the background. So anyway, I asked him once “So you dont like me in that way at all, right?” and he said “Yeah maybe I do a bit”. This was a couple days after he broke up with his GF.

We met up the other night with him and one of his friends, he started putting on the moves-he would tease me, and when he thought i was taking him seriously, he put his arm around me, this happened three times, the other two times he rubbed my arm and pulled me in closer and rubbed my back.. He has never done such stuff before.

He also invited me to his house, and payed for my dinner, once again he has never done that. He also kept playing with my hair. At one point he wanted to see if I could stand on his shoulders(just mucking around) so he sat down and I stood up on the bench and the whole time we were agruing about how to do it he was holding my hands :S He hasnt actually said “yes I like you” but his body language seems to betray him.

Also, recently while on the phone he was all quiet, I txted him afterwards asking “are you mad at me?” and he replied “Nah, luv u heepz”. So everything is pointing towards->Yes he likes me.

But was he just showing off to his friend, or does he like me but doesnt want it to look like hes moving on too fast?
I like him alot now and he knows it, but this is really frustrating me!!
