Does this girl like me? How do I know when someone likes me? I really like this girl, what do I do? - what does a model do when period

It is the girl in school, at meinem 2 and 6 Classes is time. We talk when we are in the class, and she has my phone number, but rarely talks / texts to me. Always make sure that I'm nice to her and she smiled and looked at me, but not touching the hair or something on his hand.
One day she told me of 2 guys who know how you like it. Im not sure if she tried to make me jealous, or she was not interested in me.
I'm almost always tired, and so might think I'm going to try to ignore it, but I am not. I like this girl, but I do not respond well to girls (I'm pretty geeky).
Sometimes things do have in common, such as delays in our book projects, etc. It is also very friendly to everyone, so Im not sureIf I like it.
It is not popular, and it's nice, but I love it. It is a model thin and small breasts, but I have no interest. I am a man of 200 pounds and I hate my weight, but you can hate her small breasts.
