im living through the same thing bro. really there is nothing u can do. if u confront her she'll just turn it around or think ur bein mean or ganging up on her. i still havent figured out anything to do. basically u just have to turrn around, say fuck it, and walk away until she cools off. also watch out for addiction with her. depression pills or anything. if she gets an injury or something and gets pain pills watch her very carefully. trust me... anyways hope things get better bro later
