I'm sorry you are having marital problems. Keeping communication between the 2 of you is very important.

"For those things she admits need attention, there is a lack of will to fix them, so I just don't know where this will end up." - Could it possibly be that she has no idea HOW to fix the problems that she admits to? Many times when we don't know how to fix something, we sweep it under the rug and ignore it. And, many times we are afraid to face the work that we need to do to fix the problem...it can be a scary reality.

I do wish you both well! Good luck with everything!
