Does it seem like he likes me?

So, I used to like this one dude named Leo..he doesn't go to my school anymore doesn't talk to me anymore. I'm not completely over him tho cause I liked him for so long. Anyway, there's this guy Will. He's really nice, ive known him since 9th grade when he introduced himself to me in biology cause he was new. I think he likes me, but I'm not sure. I would always talk to him about Leo. So I needed help with physics homework, so I asked him to call me and help me and he said ok when he got off work. So he called me, and when he answers the phone I started freaking out and laughing! And he goes are u alright? And I was like hm? And he repeated the question then said I thought u were crying or something. And I was like no I was laughing! So the whole phone convo was akward and I didn't really accomplish any real answers on the hw. He also said he was sorry he couldn't be of any help.. So today in gym he tried to say hi to me according to my friend and I ignored him! But then I said hi to him the second time. And then I saw him in physics cause I stayed after the bell and he was like excuse me your in my spot Jess:) and I was like panicking for no reason! AND, my friend had asked him what did he think of me. but all he said was "oh she's cool"...but hes also not the type of person to be giving out his business to everyone. its like part of me gets anxious bc i think he likes me and i dont like him like that, but part of me kinda likes him too bc of his niceness i guess. do i like him?? or does he like me? :/
