We've been married 13 years, together 14 and yes still at home. She won't leave the security I provide until she has a replacement.
W plays the role of the "poor me" victim extremely well, so she can get lots of support, its just all from people who don't really know her or her sister who is in Florida and is almost as screwed up as W is. It doesn't hurt that she is exceptionally attractive so she can get all of the disfunctional male attention she wants.
Its typical of a narcissistic personality that she doesn't take any responsibility for her own garbage. In her mind everything happens to her and is not caused by her. Her favorite term is " I can't" rather than "I won't". That way some unseen force is always preventing her from doing something.
Stand up for what is right, even if you are standing alone.
