Can u pls help me? Does she like me? pls help, no one is answering :,(?

[me]

There's this girl I really like and lately I'm getting the feeling she likes me back. Whenever im talking or say something in class that's relevant to the discussion she will turn right round to look right at me while I say it, if I look back at her or catch her eye doing it she will look away really quickly. It was my birthday the other day and as soon as I walked into the class I share with her, she grinned at me and said "todays ur birthday isn't it?" and I said "yeah" and so she grinned wider and said "Happy Birthday then!" and sat down kind of embarrassed.

It doesn't sound like much but she is always really shy around me and it is really rare for her to talk to me first cos she just goes bright red and smiles at the ground, and she isn't shy around other guys. Also she doesn't have Facebook so she must have just remembered my birthday on her own without it telling her.

She is the most attractive girl in school and every guy has a crush on her, I'm not as popular as her and we hang out in different groups but her mom told me like 3 years ago that she had a crush on me back then. She has done a few strange things in the past like appeared at my front door holding my cat saying "um, I think this is ur cat, I saw him over there so I brought him home, anyway, bye" and hurried away embarrassed again (this was like a year ago but things like this happen very occasionally).
(btw we're both 17)

What do u think? Does she like me?
I will choose a best answer in 1 hour exactly pls help

Dude how the hell do you expect us to know? If your living your life and can't tell, you think random strangers reading a paragraph you typed can?
Why don't you ask her to hang out with you and see what happens? Ask some mutal friends leading questions to see if they know. Ask her mom agin if you know her so well.
