just tell her what you feel. if she thinks you don't trust her, tell her that u do and then try to prove to her that u do. if she thinks u hate her, tell her u don't and try to hang out if you can, try to hang out with her more than what you already do. just tell her that u want to stay friends, but u need some time right now to just do your own thing. if she doesn't understand, then come back for more help.
