I have been dreading this same conversation. I have been paying some of W bills because I don't want to have the discussion about separating them. I don't have an answer for you but as time goes on I realize more and more right now she doesn't care about me only herself so I am concentrating on me and my Daughter and I will be telling her to pay her own bills very soon. I can't keep living like a doormat.
