How do I get my husband with Alz to like and be nice to my Mom? We all live together.

Hindsight is 20/20 vision, of course, but it sounds like you made the wrong decision last November. Moving in with a mother who is mean to you and whom your ill husband does not like was not likely to work out well. And it didn't.

So, move out. Help Mom hire some household help, or help her apply for aid so that she can afford it.

You have your hands full caring for a husband with dementia.

Mom's house,finances tight, had to quit my job to take care of husband. Mom needs
help around the house. I do cooking and cleaning for her, drive her to dr's etc
We have all been together since last November. Husband diagnosed fall of
2010. We came to visit and she asked us to live with her.

It is a nice wish that you call get along, but I don't think it is going to happen.

Are you living in your house or in Mother's? Does mother also need care? Hubby has dementia. What are Mom's impairments? You say she has been mean to both of you. How does it happen that you are living together?

How long have you been together? How long ago was Hubby diagnosed?

Sorry for all the questions, but if we have a better idea of the situation perhaps we can offer more specific suggestions.

Separate them. You cannot reason with Alzheimers. You cannot change your mother. Move out.
