Should my mom divorce my dad?

For the past two years, my parents have been fighting on and off…

the main reason for the fights is that my dad does not do anything for the family. He doesnt even get any income for the family. It is all my mother who works 8 hours a day… He also doesnt think that it is his duty to do something for his family.

My mom is not happy with him. She sometimes wont talk to him for weeks on end. She has a lot of reasons for wanting to leave him. My dad isn’t abusive or anything, but he is rather…annoying, (or psychologically abusive?)..i suppose… he always glares at us when we (my mom, my brother adn I) get infront of him and the TV, or when we’re too loud in talking, while hes doign something.

What Im trying to say is, my mom is not happy with him. She wants to leave him, but she is afraid that if she kicks him out, he will get sick, since he wont know how to live, and earn income.. She has a kind, but strong heart…thus she is torn in not being happy the rest of her life, or in a way, ruining my dad’s life…as we are all he has really, he doesnt know any friends, nor is he close to his parents and sibling.

Well.. I just wanted to ask you guys what the possibilities my mom could do! Should she divorce him, and he may possibly get seriously ill (as he is also rather old)....or what? What is out there that could make my mom happy, but not have my dad get ill because he has been separated from his only connection to others? Could my mom give him enough money for him to get along…? I dotn know about this stuff…
and sorry the description is so long!
