Mr.Manish
I have read the analysis in the vedic system. I express my views in KP system.
Your 7th cusp (marriage) sub lord is Mercury. Mercury is in 11th house in the star of Moon (lord of 5th) in 2nd house. Mercury is in the sub of Saturn in 12th house. Saturn is signifying 7th house through his star lord Rahu in 7th house. So Mercury is signifying 11th, 2nd houses and 12th house & 7th house through his sub lord. 2nd, 7th and 11th houses are needed to give marriage. Here 12th house also supports marriage through the sub lord. Hence marriage is promised in Mercury bhukti.
Dasa lord Rahu is in his own star in 7th house and sub of Venus in 9th house. Rahu is aspected by Saturn who is the significator of 2,7,11 houses. So Rahu promises marriage with some delays.
Saturn, Moon connection gives delays and postponements. Saturn is in the star of Rahu and sub of Moon. There would be delay. Saturn will not allow other planets to give the results. He has to give.
So you will get married in Saturn antara which is from 06-11-2025 to 03-4-2026. There are feeble chances in Rahu antara and Jupiter antara also. As the transits agree in the above period, I have taken Saturn period.
Note: In KP method, Occupant of a star is stronger than the planet. Even though Jupiter is in 8th house, it is stronger than Mercury (7th sign lord), as Jupiter occupied Mercury star. Like wise all the planets work by its occupancy in a star.
Good Luck
