Does he have a crush on me?

I have a friend whose been with me through a lot. The past two weeks ive noticed a change in our friendship. It went from just friends to when were with each other its a flirt fest and he looks at me very longingly and he hasnt had that strong of that look until recently. He also has been blushing a lot recently. And apparently smiling and getting all excited when he sees me. On sunday I waved to him and he waved back then awkwardly excited waved a second time and almost fell out of his chair. Lol. And he said that he was going to try to be better for me. And that he is going to work on spoiling me with everything I could ever want. He hasnt really ever said those kinds of things to me before. But weve always been open and close to each other and have a very strong connection. He will walk very very close to me. So close that we are touching sometimes. And he will randomly come touch my hands and just find a reason for touching my hands. I always have stupid jokes and he always laughs at them and he will always look at me after he makes a joke. I apparently have never noticed when someone had a crush on me and I havent actually had a crush on anyone either. Is that what happens when someone has a crush on you?
