I was in a similar situation to yours a few years ago. My ex-wife was getting worse at the time both physically and mentally. When she returned home from in-patient care, she told me that she wanted a divorce to "spare me from seeing her suffer." I was devastated. I fought as hard as I could to make her see that I loved her and wanted to work things out but after a year or so. I had to let her go and hope that she found peace and happiness.
I can only say that it will get better eventually. Just know that you have the love and support of friends and family members that will help you greatly in your time of need.
