I have been there before too, my ex husband openly told anyone that I was his wife and he had needs and I had no say in it and he raped me as much as he could, he even one night ripped my pants off of me and raped me, he kept saying it isn't rape cause were married, the next day i got help to throw him out, he took my son for a month until I got my lawyer geting a order to get him back, My ex tried everything to make it hell for me. I had help and support from my friends, family, Master 9804, and a very special friend who offered me anything that I needed. That was 5 yrs ago. I still haven't gotten over it all completly but I'm not as jumpy or scared anymore and I love sex now. Master9804 loves it too

.
My advice is get out of it because nothing will make him change, you own your body and only you, her friends, family and the law will help. For her own sanity she needs to get away before she starts to think only way to get out is the one way no one wants. I hope this helped.
