Suggest Treatment For Aggressive And Abusive Behavior

My boyfriend s father had a stroke 3 years ago. He has lost the use of all but his left hand but it is very week. My boyfriend takes care of his father during the day and works at night while his mother watches his father. This is taking a toll on my boyfriend’s health in many ways. Before the stroke, his father was a mean man who cheated on his mother and put my boyfriend down, not to mention gambled away 100,000 dollars in life savings. Since the stroke, the father is even worse. He constantly puts the family down and threatens to kill them. On Friday, my boyfriend said his dad threaten to kill him 4 times in the most horrible of ways. The dad has also physically hurt his mom and sister with his good hand. The sister does not want to take care of the father and goes off with her boyfriend, leaving the mom and my boyfriend to take care of him. The cops have been called numerous times and they and a lawyer have said that his mom should divorce his dad and turn him over to the state. His mom has not looked into doing anything. My boyfriend wants out so bad. He is depressed all the time, has gained weight, and barely gets any sleep. The family feels hopeless and every time my boyfriend brings up that he wants to move in with me and start a life, his family thinks he is a horrible person. He has given up 3 years of his life and contributed to the family s finances while the sister has done nothing and the mom wants to be a victimized wife. My boyfriend does not know what to do and neither do I. What can be done? The family doesn t have much money to put him in a home but they shouldn t be subjected to the Dad s cruelty. Where can we look for help?
