Step Daughter problems (need advise)

My opinion don't hate i would sit your ole lady down and have a talk tell her whats on your mind and your plans for the freeloader and end it with get on board or don't let the door hit her in the *** on the way out too,that might wake her up. I've told my ole lady numerous times i'm the bread winner here you don't work and bring income into this home so i'm the boss [most of the time] if you don't like it theres the door hit it she's still here.I don't have your problem both my boys work pay their bills buy their food paying for their college ect.
