What do you think his intentions are? help please?

I’ve started to have feelings for one of my close guy friends and I have no idea how he feels about me, it changes all the time and its so confusing. Theres days where im like yes he likes me, and days where im like of course he doesnt what was I thinking? Here’s why: we’ve been friends all throughout highschool (were seniors now)he had a girlfriend for about a year and a half from a different school and they broke up a couple months ago. Even when he was with his girlfriend he would flirt like CRAZY. He sits behind me this year, and sometimes he’ll play with my hair or write his name on my shoulder, call me babe etc. He jokes around with me a lot and teases me, we make each other laugh and We talk all the time in class, and online too about anything at all. We’ve been mistaken as a couple a few times (once by a teacher!). We both play volleyball, and at first he wanted me to go to every home game and some away games, when I missed a couple, he acted all hurt saying he was looking for me in the stands. then he also asked some other girls im friends with to go too, to start a cheering section. I’ve called him to hang out twice, but it fell through. When we talk online, I usually start the conversation. Over spring break when we hadn’t seen each other in a few days, he called asking me if a test we had taken in a class we have together was scantron or not. The test was the week before, he sits right behind me in that class and knows we never pay attention or do anything in that class, and now he expects me to remember something like that? my friends think he just wanted a reason to talk to me but im not sure. Im good at art, and he asked me to draw a portrait of him and I did. it’s now hanging by his bed. Im just so confused about how he feels and I cant just ask him how he feels because our relationship is so jokey and I dont want to ruin anything. what should I do?? How do you think he feels about me?
