What does it mean when you cuddle-ish with your guy bestfriend?

so, my best girlfriend and my best guyfriend and I hung out. We dropped her home and he was going to drive me home. It was 11pm at night, but I wanted to stay out later with him so we hung out at the park near my house. We were hiding in the slides to block the wind and he just started to lean on my legs and waist. He kinda leans on my sometimes+give each other piggyback rides and I don't care because I want to be more than just friends with him.. I like him! Then a bunch of people came to the park and we wanted privacy and stufff, so we went to the back seat of his car. I was just siting there alone and trynna rest cause it was 12am & he comes leaning on my leg and waist again. I mean, I playfully pushed him off not to make it seem like I like it, even though I did. Then I was kinda tired and I said his seat covers were sorta hard & uncomfortable. So, he sorta told me to lean on him. I leaned on his shoulders, but it was kinda bony so it was uncomfortable and I got off. He said it made him warm and wanted me back & I was it was uncomfortable. Then he pulled me back and put me against his chest and his arms across my body. His chin was right on top of my head, while he gamed on his itouch. He stopped at times and we talked for awhile.. (: It felt good and we just stayed like that for 2 hours. How do I know if this means anything more than just friends ?
