Is hatred a big win for DIL's? Demanding your husband cut his past out of his life?

Your DIL is playing the "Prove to me how important I am" game with your son. He has to "prove" his love for her by doing what she demands,no matter what it does to his family. She wants everything to be about her and her little drama filled world. You can't win with people like this,if you cave in and do what they want,they just change their mind and still tell you you're wrong.
