Does he just like me as a friend or is he shy or what?

So i'm really confused if my friend likes me. Sometimes he'll do things that make me think he likes me then other times he'll act like he only likes me as a friend. Some things he does to make me think he likes me are that he always initiates the conversation whenever we hang out, he will sometimes touch me (he likes to warm my hands and play with my hands and my hair), he likes to pay for my food all the time (we hang out with other friends every Friday night and we always eat at Denny's), and one night when we were at Denny's me, him, and two other friends were talking about stuff and he randomly goes "did you want to be more than friends?" than like 5 seconds later goes "no i'm just kidding." The thing is he makes no effort to be around me. For example I haven't seen him in over a month and he made no effort to contact me. I ended up going to his house because I am friends with his sister and when i got there he acted really weird and only talked to me for like 5 min. and then he went and stayed in his room. He hardly texts me (idk if that's bad) but when he does he's always the one to text 1st. He has asked me bowling once and to the movies 3 times but all those times he either brought his bro or sister with us so I guess they weren't really considered dates. I think he might have done that though because he's kinda shy and once when we were at the movies he told me he was nervous. Anyways does he like me and he's just shy or he doesn't like me at all?
