Looking at your horoscope Mars rules the 7th house of marriage and Mars is debilitated in your horoscope. Saturn aspects the 7th house. Ketu (south node of the Moon) is posited in the 7th house. Marriage after 25 years is indicated in your horoscope. Relationship problems are indicated in your horoscope due to the planets in an inimical position, therefore it will be important that you match your horoscope with that of the partner for a good healthy married life.
