Dear Raghu,
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.
Mercury which is also 7th house lord and dasha lord conjoins 6th house lord venus in first house. 8th house lord undergoing saturn transit gives harsh ego changing situations to work upon. Jupiter transit in 7th house in Mercury-Jupiter Dasha will bring settlement.
