@rubbing your arm against him, That's a great start! That just sends that vibe down me when a girl I like does that to me. It totally starts to lead to more and more touching, and the chills that go down my body are just awesome! Not only that, I totally know that a girl is into me when she rubs her shoulder against me for about one second and then steps away from me with a smile on her face. I totally try to get back closer to her, so she will do it again.
You should totally try to hug him goodbye if the opportunity arises. Just don't push it and come on to strong. If he likes you, he will definitely start to make his move and that first hug will feel like your skin is catching fire, and your heart is racing, and you got those massive butterflies in your stomach.
Patient is key.
Best of luck!2
