I would like to share my perspective on marriage for this chart with my little knowledge. Sorry if my analysis is incorrect.

Although the 7th Lord (Venus) is in Own sign in D1 but he is in neecha in D9. Unfortunately the Asc is Vargothama that makes the Venus as 7th Lord in D9 as well. Though Rahu is in 8th place, but he is in 7th Bhava and he is close to Venus. All these are not a good combination for marriage.

The Venus is Star lord for Sun, Moon and Mars hence the marriage may not favourable in these dasas. All these dasas came one after the other.

Jupiter is at 15 degree and Venus is at 28 degree. So taking deeptaamsa into effect, the Jupiter will not have strong aspect on Venus.

Pariharams for Venus might help.

Thanks for reading.
