Wow!! They say MLC can easily last a decade, but I think your wives issues are just bad behavior on her part. Did you have tell her you weren't going to put up with being treated like this? Does she have a job currently?
Sounds as if you let her cake eat for the past ten years and she thinks she can do whatever she wants, whenever she wants. She does say the normal spew for these A loving people. I am sort of at a loss as to tell you how to sort out this mess. I would advise focusing on you and getting yourself to a point where you feel good in your skin. I would stay dark on her. It sounds as if you have always been her backup when things go wrong. You don't deserve this, no one does.
Ask yourself, do you really want her back? She has been in and out of this for 10 years, have you seen her resemble the person you feel in love with during this time?
Sorry more questions than advice. Keep posting and maybe we can break this all down a bit better.
