Kinda confused about a guy.?

Ok so this guy I know used to like a friend of mine but now they like never talk and I think he may like me now. First off a couple days ago after church a bunch of the guys were hanging out talking and I was standing with his sister and he was talking with the guys but came over with his sister and I. Then someone asked me where my sweater was and I had forgotten it. So my guy friend took his off and handed it to me but I told him that I didn't need it cause I didn't want him to get cold and he said he would be fine. So I took it but didn't put it on then handed it back but he had done this before with his beanie and a pair of gloves while playing air soft. He also has been texting me more often. He also offered to buy my soda but I kinda didn't let him. Now I feel kinda bad for not wearing his jacket and not letting him buy my soda. What are your thoughts? Sorry about the way long thing.
