Mil and husband

My mil nowadays keeping trying to find trouble with me. Whatever I buy things for my lo she will say something and than make my husband unhappy and keep telling my husband this and this. Since my fil passed away she keep telling my husband to 'be her husband ' ever since than I don't even have the chance to hold my husband hand. Whenever we go out she follow. Everything also dun want to do. Always disturb my lo, since she can go down buy coffee for herself why can't she buy her own food. She is 60 . My husband will scold me whenever she talk bad about me. My husband used to love me alot but now no more. What can I do??????
