Could somebody please help me with this girl?

Right here goes, theres this girl I know and i really like her, I mean shes like the most beautiful girl i’ve ever seen! But every time we get closer together (become even more friendly), she’ll get a new boyfriend =/, like I spent my whole holidays speaking to her. First thing I know when i get back to school – I find out she’s with someone.
At first I wasnt bothered (still liked her anyway), but last night I was speakin to her on a website. Next thing I know I get a text of her (I didnt even have her number, nor did she have mine), which made me think, is she interested?! Mainly because it came out of the blue and she was asking people for my number. it may sound like nothing, but if you reply with a question on the whole situation, ill answer it most relevant to the situation..! :), please help, would make me happy.
