<human>: My father has been in an abusive relationship with an alcoholic women (lets call her Marge) for the past 15 years. He used to be extremely productive and had several hobbies, but for several years now his drinking has gotten progressively worse and he doesn't do much of anything any more. 

Marge has a severe alcohol problem. She drinks about 5-7 days per week, smokes like a chimney, and encourages my father to drink. When she gets drunk enough, she tells him he's stupid, that he's old and ugly, and she hits him. His self-esteem has declined so much that he stopped going to the dentist and now has no teeth, and hasn't had his hair cut or his eyes checked for many years. 

It pains me to see my father like this. His house is falling apart and it looks like it belongs to a hoarder. I worry about his health because I don't believe he is getting regular medical care, and with my family's history of heart problems he's at high risk for stroke and heart attack. I want him to break up with his spouse and find someone else, but I think his self esteem is so low that he's afraid that if Marge leaves him that he'll be alone for the rest of his life. I'm only 25, so I'm not exactly financially independent enough to take care of him yet.

Does anyone have any experience with this sort of thing? Is there anything I can do? I've tried talking to him, and he has expressed his unhappiness with his relationship before. I can't convince him to break up with his spouse though, and I'm afraid that if I push too hard he'll resent me.

Can you summarize the given text in a few sentences?
<bot>: My dad is being abused and won't take care of himself and I want him to leave his spouse and find someone else.
