In the current dasa of Jupiter, possibility of divorce is low from your chart. Don’t know about your wife’s chart.
But you have Shrapit dosha (Saturn + Rahu) and Pitru dosha (Sun + Rahu). These could be contributing to your desire for separation.
Take remedial measures for the above, perform a Uma-Maheshwara puja jointly with spouse. These could save the marriage.
Unless of course if you have started adoring someone else (which is also likely in this dasa).
