Horrendous marriage... Options?

Female friend 38 in a verbally and emotionally bad marriage of 13 years. Husband admitted to an affair recently that he says was 9 yeas ago. Although he admits to speaking with various women currently. He works, she doesn't. He tells her to get a job, but offers her no advice or istance in finding one. She has one son 18 at home from a previous relationship. Her son is unfortunately living in a fantasy world and not working or even looking for employment. She doesn't drive and has no savings. They live in a house they own in a not so nice rural part of the U.S. about a 2 hour ride from New York so public transportation is not great where she is. A city bus here and there. She has no real friends or family nearby. She just stews in her misery in that house day after day knowing that he's cheating, lying, being stingy, and rarely having a kind word for her or her son. She calls me frequently and tells me of the nasty things he says and does. I can tell she nags him a lot so he's obviously got no love for their marriage either. She claims to want a divorce, but she's go no money to even get a face to face with a lawyer from what she told me. Says they won't give much info on the phone either. What options does she have to live a life that can even be considered somewhat bearable? I tell her to just get out of the house sometimes or volunteer someplace. How can she get out of this pickle? She's in a real mess and has put it all in my ear over the phone for the last couple of years.
