The marriage unstability in your life will continue for many years, at least 5 years more. If lucky, you can resolve things in the next 2 years.
Your ego, especially attached to partners outcome and expectations are misplaced and you need to seriously work on them. The next 2 years can be used to resolve issues and make your marriage better.
Divorce is not a strong indicator in your chart. Hence there is hope to come out of this crisis through your self-realized efforts. Best wishes.
