What does this hug mean?

So, last weekend I went to a swing club. I met this really amazing guy there and we were practically together the whole time. The first time he asked me to dance I was petrified because I like him a lot. But then I started getting more comfortable around him. By the end of the night he had hugged me 4 times. The first time it was a "side to side" hug. Like, our sides were touching and our arms were around each others waists. The second time it was the kind of hug where your feet are about 6 inches from the person you hugged- it was a pretty short hug. The third hug was from behind- he surprised me by grabbing my waist- I kind of squealed. And the last hug was the best hug that I have ever received... I was saying good bye and it was around 1 AM. He takes me into his arms and there is absolutely no space between our feet. We were hugging so close that a piece of paper couldn't fit between us. We must of hugged for about a minute. It was fantastic. But could you please tell me what this means? Does he like me?
