I hate being in love...help?

I'm 16 and a biual boy and the boy I have a huge crush on and I'm sure in away feels the same way about me; trust me I have my reasons; anyways for some reason I tend to get jealous of him sometimes, saddened and miserable by constantly thinking of him but at the same time glad to see him and sometimes I wanna like push him to the floor or something only because I sometimes ume he talks about me or gives me looks and if I did push him I'd feel better, idk if that's normal or why I think that way but I wish I didn't like anyone right now. Help or advice?
