Is my BFF really acting like a best friend?

Just leave her in the position she is.How much you try to convince her,she will not listen.I once had a best friend,before breaking the friendship with her ,she did works like this to me.She was avoiding,I confronted her no matter what happened.It led to our friendship break up and I would suggest you.........why dont you make some new friends and try to enjoy with them.When you get free time,try to talk with your best friend and ask why she behaves like that.You should not only hang on to her.Make other friends and talk to other people also.Make yourself busy so that you wont feel lovely.
