Is it normal i get a tingly feeling...

I seem to have fallen inlove with a boy i met not long ago, when ever im at school he's all i can think about, he goes to a different school to me and i met him when i was out having a meal, i get a tingly feeling whenever he chats me and i think ive fallen in love, how can i slowly drop hints that i really like him and to see if he likes me with out being too forward? Is it normal he's literally the only thing i can think about, and when i say only thing i mean it im constantly MAKING my self focus on my college/school work, is this normal?and any tips?:/
