The problem is not your mother in law, the problem is your husband. He visits her everyday and talks with her. Now he wants
to live close to his mother. When he visits with her her is telling her your family business, and this is how she knows everything. She
is thinking the two of you want her advice.
You must look hard at your relationship with your husband. Why did you marry him? Was he like this before you married?
Do you like his family? And do they treat you well? And remember this - this woman is his mother, the woman who raised him and
made him the man you fell in love with. Also remember that
a man who respects his mother, will also value his wife. 
With that in mind, you have three choices.
1. Make his mother your friend and become close to her. It does not look like your husband will change, especially if it is his idea to
move to be near her.
2. Refuse to move and force your husband to move to another place. This is not likelly to work, and he will still visit his mother almost
daily, and resent may you for the conflict.
3. Argue with him daily over this, which is not going to get you what you want and probably end your marriage.
You must decide if you love your husband enough and if being married to him is worth putting up with this. Whatever you do,
talk, not argue, with your husband and ask him why he thinks this is a good decision. Have good reasons why you don't like this idea,
but never raise your voice about it. After the decision is made, do not bring it up again as it will cause much damage - don't make him be unhappy to come home.
If he family treats you well, be grateful and become more apart of their family. this will be a tremendous help when the two of you have children, are ill, have an emergency, etc. Being close with his family will also reinforce your marriage. A man is not likely to treat his wife badly if his mother is near enough to hear all about it.
