Trust me. Hope is not all you have. Time is what you have.
I admit that the separation is a tricky thing, but it may be the shock she needs to jolt her out of her funk just like you did with yours. Plus she can't keep putting the blame on you as to how miserable her life is.
Again, the separation does not mean D. And besides both of you will be doing things together with your kids, so it's not like you're never to see her. Give her some real alone time. Let her miss you.
Right now, I just see your M slowly slipping deeper and deeper because it's obvious she's getting colder and colder. You have to do something drastic before her temperament freezes over and you don't have anything left.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
