so why are you keeping her secrets? why are you accepting responsibility for her actions and letting everybody see you as the bad kid? if you are worried about her, why not let your parents know what is going on so they can take actions to stop it? instead of being an accomplice, do something to change it. it is not like you owe her anything. she is not being kind to you. you care for her and want the best for her. you do not want to see her go down this road. take action to change it.
