Is it wrong of my to not want my future mother in law to live with us?

My future mother in law is in a bad realtionship and i understand that she wants to get out but we have tried to get her out before and she wouldn't come. So now she wants to move in with us when we get married. My man and his mom are asian and i am white and she doesn't speak very much english and it really puts me in an akward position. Plus i think it is our chance to start our life together and she can come and visit. What i don't understand is i offered to help her get a house in Wisconsin where she has three other daughters and four granddaughters and she doesn't want to. She doesn't want to move to alaska by herself either (she has a bunch of sisters and stuff up there) and she has been begging us to move there when we get out of college. She just wants her baby boy and thats it and he thinks we should do whatever it takes to make her happy! I think im presenting a pretty good compromise offering to help her with bills and a house anywhere but in my house rite? HELP PLEASE!!
