financial and family problem.?

[M P]

My mother has left my father numerous times, but always returned to him. She always left him with the help of others. My mother's siblings always gave her money, or a place to stay, etc. And no matter how much my father abused her physically and mentally she'd always return to him. And I was always there to witness it. Well three years ago I left home and got married. I have a part time job and going full time to school. My husband is helping me financially because I cant afford to pay for school, rent, food, gas, etc. He pretty much handles everything financially. Well my mother has left my father again and has asked of me to ask my husband to help her get an apartment with his name on it. Currently she has no job and two younger children. Her income is based on government help. After much arguing I finally convinced my husband to put his name on his apartment and take a gamble helping her. But now that he said yes and after much thinking I feel terrible putting him in that situation. Its his money, his credit, his savings. Not mine since I dont have an income to support my mother. But before he changed his mind I felt terrible not helping my own mother. I want to say no to my mother even after my husband said yes. But how can I do that to my own mother. And if I say yes how can I do that to my husband. Im not sure what to do and feel terrible, gulty, lost, etc. What whould you do if you were in my situation. I appreciate any advice. Thank you.
