Does he like me?...(Did I mention we are 12 years apart?)?

Ok so this guy is 12 years older than me. He always tries to make me laugh and he ALWAYS makes major eye contact with me, and talks to me about all different kinds of stuff, and he always listens to me. Then when I was with him and other people I came in and he says sit down and pats the seat next to him (he has done this multiple times), when we sit next to each other on the couch he smells strong (good smelling) and our legs, arms, or shoulders are almost ALWAYS touching. There is more room next to both him and me but he doesn't move over. He also seems to mirror me a lot. When we were in a room listening to a message (on separate couches) he kept looking over at me and smiling or making faces, also sometimes I would see him and he would turn his head quickly. He always comes over to me to talk and one time he was kinda far away and I look away and look back and he's closer, then I do it again but I watch him and he moves closer still! He also brings up the fact that he cannot get a girlfriend often. One time he got this green lantern ring and puts in on his ring finger and says he's getting married and he tells his friend that his fiance is the perfect girl for him and then he turns to me and says "but I don't who that IS yet, lol" , and later he says "its hot in here" and starts unbuttoning his shirt (p.s he had another shirt under neath). Also when we were sitting next to each other our knees were always facing each other. So does he like me??
