I would give anything for an indefinite separation! Unfortunately, my MLCer still has to have the D.

Your W is likely WAW/MLC. If you can wait another 1 - 3 years she will likely come around and be at a point where she can work on the marriage.

Most likely she cannot at this point given her current mental state. She is sick. Give her the time if she will let you!

Anyway, just my $.02...
