Dont know what to do about a sick girlfriend...

most of the guys have proven a point, but dont fell obligated to stay with this chick if shes making u unhappy. What matters here is what you want, not here and def not anyone else. You have to step up and take charge. if she acts like a bitch, then dont answer your cell phone. you call when you want to. Also, makes sure she understands that you arent happy so u two can work shit out. And still if its not working, then dump the bitch. Plain and simple
