Still chill with other girls. When she is in a relationship you should retend that you don't care.

Like I said, I'm bad at making friends and she's not really my friend she's just nice.

You have to take risk boy, you need to impress her, by any means, gain her attraction, without doin that, you are nothing boy.

Just look at the big picture try to change your lifestyle go to school events sports games etc meet some more people and adapt, from your post its almost as if your a hermit? but no one should have to live that way, just simply spread the way you think and act and everything will be alright.
