What do i do about this girl?

[CH like Charley]

You forget about her. It's extremely clear that she is not a good friend or anything else to you. Even if she is nice sometimes people deserve to be treated well all the time by the special people in their lives. Seriously this relationship isn't a relationship and sounds like plain drama, not worth anything. Focus on your life and doing things you like, not people who don't appreciate you. Start living your life without worrying about what people like her think and you will find better people a lot sooner. Good luck.
