Affiliate Marketing Secrets

I am a sophomore in high school. I am fifteen. (That wonderful age where the most irrelevant dramas take up 90% of your mind and ruin your day) I am a lesbian, and their is a girl whom I really like.
I have never had a girlfriend, (and neither a boyfriend) so I am a little clueless on how to approach her. To make matters worse, I am not even sure if she is gay herself. She has that gay air about her. You know, that homosexual energy. She does dress slightly masculine, (which I understand really says nothing about a person’s sexuality) and her hair is cut short. I know for a fact that she is single, and she does support gay rights, the main question here is wither or not she is gay herself.
She is a new student. (junior) She has only attended my school for a couple of weeks now, and she still has that “lost” attitude a person has when at a new place. It seems as if she has not found a group of friends or niche, so this really is the best time for me to make my move. I would just go up to her and strike up a conversation, but I am afraid that at this point it would too awkward. You see, for the past couple of weeks she and I have been sharing these odd glances at each other. I am unsure as to how to explain them. It is as if their is something hanging in the air between us, yet it may just be me imagining things.
I am simply confused as to what to do or how to approach her. I have lunch with her, and I have one class with her. I am just too afraid that she is going to be weird-ed out by me. What do you suggest I do?

I love to travel and a lady recently told me she got free flight tickets just by racking up flyer points.
How does this work and what is the best way to do this? and best company to get affiliated with?
Thanks!

I live in Philadelphia. I’m trying to find a major in web development, not so much the design part (wouldn’t mind it, though) but the coding (php, jquery, and all of those fancy stuff including basics like html and css, etc.)
The only college/university I could find was Drexel, but Drexel is a private university and it’s EXPENSIVE. I need to attend a state affiliated college but I can’t find one with the major I want. I talked to my counselor and he seem a little clueless about web development.
