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.

Oh is very sad to heard that, your husband will be vary stress. Mother and wife both are important person one is a woman who feed him from young to and adult and one is a woman stay with him to old. Are you staying with your MIL if yes maybe move out with your husband stay contact with her. Or you are not staying with her let your husband visit her his own you don't follow.
