How do i make this girl my girlfriend?

[Bass]

OK, i'm going to introduce myself. My name is Bassel i'm 15 years old and i think i'm in love. Since he beginning of the year I've been wanting to speak to this girl and get to know her because she seemed nice and i had this weird attraction to her. Recently she started a conversation with me because she noticed that i was in all her classes, but that was one of the only times I've ever spoken to her. I was wondering if chatting her on Facebook was a good idea, and after i get to know her and i feel comfortable starting conversations with her, how do i make her my girlfriend? Thank you for reading, any help would be greatly appreciated keep up the good work.

what you could is tell the girl you like her. if you are scared of what she'll say, say it on facebook or something!!! the girl is not gonna get mad that you like her and if she does, it's not your problem because what the big deal about a guy liking a girl?
