<human>: I have a (large) crush on one of my good friends that is already in a relationship with someone else.

Age ~16, I met this really nice girl around six months back and we started talking, found that we had common interests, views and had a good time talking to each other. After around two weeks she suggests that we hang out together.

 So we start hanging out and become quite good friends, but nothing *special* yet, at the same time she meets her current boyfriend and goes out with him while still hanging out with me. I assume that at that time she viewed me as a good friend and enjoyed my company.

As time goes on we stay good friends, I buy her presents, invite her for lunch etc, she seems to treat me as she would her other friends but as she is currently in a relationship I didnt want to do / tell her anything.

Now that its been six months, and I've been stuck like this, Her current BF is not too nice / friendly and is not in the more academically gifted side of school (While she and I are to a certain degree more so)

Does anyone have any advice on what I could / should do?

Give me a shortened version of the text
