I have a friend who always dump me, and I cannot stay away from her because she knows all my secrets. What should I do?

Wow is this a coincidence.....I've got a friend too....I've dumped her cause of her continuously hurting me...she knows"some" of my things...but not most....I never get bothered if she'll tell them or not.....when I came to know her real identity I stopped telling her my secrets tho she was my best friend.....now if she tells any of my secrets what will i do? 

I will as always ignore what others say.....we are born...our parents bring us up.....in our whole life even though we are surrounded by people we still are alone on every step...so why care now what he thinks or she!  If they are bad secrets like cussing people then go straight away to those people and apologize....youll feel better and they will too....and now you friend will have no power....CheckMate!
