How do I know if he likes me or not?

So I am wondering if this guy likes me or not since I really like him. This is kinda weird for me since I feel like a girly girl but I assure you I have just been thinking about it all the time trying to fit the pieces together and I need some help. I would really like guys to answer but girls you can to.

So I will give you some things that have happened with us over the past few weeks that can help you out a bit.

So we only have 1 class together, and neither of use really have friends in it. We talk now and then but it really isn’t much. He likes showing me music most from which I like but he doesn’t know it. He really likes to tease me since I am pretty small. He will do things like hit my knee cap, put his hand on the back of my neck and squeeze until I say ‘ow’. There are times when he will put his foot on my inner thigh or corner me and then walk away. I also indirectly flirt like once someone asked me what kind of candy I liked while he was behind me and I told them I liked whatever was cream filled to which he laughed at. He told me once while I was sorta leaning over a table trying to hide my knife at school since I had to cut something and I said sorry since I was kinda rubbing up against him and he said ‘its ok I like looking at your a‘. He also likes talking about how big his thing is as much as he can. Though he said something that kinda rubbed me the wrong way. I told him ‘fk you’ and he said ‘ok when and where?… nah I am kidding I would feel bad your to small’. It really hurt and I really wanna know if he ment it. Recently we havn’t talked at all… I really want to go over to him and say hi but I don’t want to bother him. I am pretty shy about someone I don’t really know…

now finally the last bit of info and I will let you guys solve this one.

He is kinda a player and I am not the prettiest girl around so could he just be playing around for all I know…

Thanks for reading so much guys. I hope you can help! I would like to hear what you think he is thinking if there are things I should do to make him fall for me.
