I just fought with my mother in law. I am fed up of living with her and i will be asking my husband to choose between me or her. But I am scared he will choose her. Any strategy on how to ensure I get my way.

At your work place if you have foreign assignment seek it, and stay away from your immediate family for a short while. To me relationships as any other 'system' need a break too to get refreshed and recouperate.
