Does she like me? What do I do next?

[night]

Hey so today is valentines day and I have had a crush on this girl at school for ages. Yesterday I bought her a valentines card and today I went up to her and called out her name, took the card out and asked her if she would like to be my valentines. She said I don't know and then she said yes and hugged me. Then in my next lesson she asked me if the question was like if I was asking her out and I said "kinda - yes". So then she became quiet and while I was reading a book she was looking at me for 1-2 minutes. I could see her with the corner of my eye but I didn't want to freak her out. Everyone said I had guts to ask her and everyone said it was cute. I'm not sure what I should do next. She became quiet and stuff.Should I contact her through Facebook? I could send her an invite? Next weak I'm off school and I'd like to invite her to cinema. I believe she is thinking it through. Last grade/year we would hug again and she would use to say "Do you like me" but I would answer back "only as a friend" because I was shy. I used to get bullied. So after some time saying this she stopped talking to me until recently.What should I do now? I don't think I should leave it for 9 days. I'm going school again on the 24th. I don't think I should drop this now. Any ideas what I should do? Oh and I would like to pay for her cinema ticket as well. I can afford it. Any ideas on what I should do and how I should do it?
I haven't added her on facebook yet. I'm not very social online.
I've sent her a friend invite on facebook.

That is really cute give her today as thinking time and tomorrow just text her casually saying 'hey just wondering if you would you like to go to the cinema some time?' and see her response. I think she could be overwhelmed by the going out thing but she likes you and is not 100% sure

Maybe it was just really unexpected. Talk to her more about it

She might be acting shy and quiet because she liked you back and is nervous because you like her. Show her some confidence and ask her to the movies and definitely pay for her ticket, unless she wants to pay for it herself.
