I think one of my 'best' friends is just using me?

it doesnt take a genius to figure that she is indeed using you. shes a fake friend. let her go and make other friends im sure you're a pretty nice person, perhaps a litte too nice if you let your "friend" treat you like that. dump her like yesterdays trash and move on with your life. and then every morning drive by her bus stop and honk at her and wave at her with a grin on your face as you slowly drive by while shes shivering outside lol
