my advice to you ,alaways smile at her ,pretend that u listen,make her feel that whatever she says is right and u will follow her steps .this way she will not have anything against you meanwhile doing this do whatever u like and always be nice to your husband.evanually she will give up and get bored.and remember that she is a mother afterall and she always had her son with her and u just came and took him from her own point of view .and u might feel the same way when u become a mother in law.
