Why does he play wrestle with me and then not make a move? And why does he keep doing this?

So there is this guy that I have known since high school and I always had a huge crush on him. And apparently it was obvious to everyone but us that we both liked each other. He never stayed single long enough for me to ever tell him how I felt anyway. And fast forward a couple years and we still hang out and talk all the time. Well a few weeks ago we were hanging out watching movies and all of a sudden he starts play wrestling with me. And I won't lie, I really like play wrestling/fighting, I loved being pinned and thrown around (within reason) 😊. Well he's 6'2 and a marine so clearly I never stood a chance and he's far to competitive to let me win anyway. He literally could have tried anything (I probably would have let him lol) I also think he knows how I feel about him. We were hanging out for about 5 hours and we spent maybe around 4 hours play wrestling. But he never made a single move!!! He never tried anything! And granted I didn't try to make a move either (stupid me). Why wouldn't he make a move? And he keeps going back and forth on whether he likes me as just a friend or as more then a friend. Any advice?
