My gut feeling is that she wants out of the marriage cause it's all too much to deal with and she's too damaged by everything we've been through. I think she can't see a way forward. She is a very sensitive person which I think is making it harder.
Sam22,
One of the hardest things to come to terms with is the fact that our spouses (in my case, ex) are on their own road - and that road doesn't have room for us. Maybe one day it will. Or maybe it won't.
What you must do is use this time wisely. Work on yourself. For you. No one else. I talk about hobbies a lot in other threads, because they are great for a number of reasons. Others talk about socializing. Or sports. Or whatever. For me, one of the things that helped me the most were my hobbies. I told the story of how I got back into model building after BD...something that I hadn't done since childhood, really. It helped me immensely because it forced me to concentrate on something. That's what's needed. Find something that consumes your thoughts when doing it. Another was mountain biking for me...cant let your mind wonder there.
What I am saying is that you have the incredible gift of time. Use it wisely. Don't concentrate on her...concentrate on yourself. Be the best you can. Change comes from within and not overnight. Maybe she'll notice, maybe not. Either way, you'll be better off for it. And if there is another in your future, then she would also be better off.
Fair winds and following seas, my friend.
There are moments in this life when you are so confident in the rightness of your actions, that not even for a second do you consider the option that you might be wrong.
