She has stopped wearing her wedding band and engagement ring. However, I would like to keep fighting for this marriage to work, but I feel she does not want to. I don't see how someone who loves and supports her could be a hinderance to this process. Hang in there, don't give up or walk away. It'll be hard for you not to become frustrated, but you need to keep you cool as you both work through this.
Professional counselling sounds like a good idea.
No great insight from me, except that I can relate exactly to what you are going through. Cofusion abounds on my part - and I have been at a loss as you. It's difficult to see personal shortcomings right now, but self-reflection can proove insightful. Also, I think counseling is a good idea. I am a bit concerned that one spouse going alone conveys too much of a one-sided view, but I am trying to roll with it.
