Ketu in the 7th house of marriage forms the Naga dosham. It will bring delays and obstacles on the marriage front. Presently also Ketu in transit is in your 7th house leading to no results on this fronts. Ketu will move away in September 2020 after which you can expect positive results. Meanwhile reducing the malefic effects of Ketu will also help you get early results.
