Looking at your horoscope we see that your 7th house which is the prime house for marriage is ruled by Jupiter as Sagittarius sign is there. Jupiter the 7th lord aspects the 7th house which is good. However Rahu in the 7th house is not auspicious, it can delay marriage or create obstacles in marital life. This is called kalathra Dosha. You can read more about kalathra Dosha on this website.

Venus the karka of marriage is combust and therefore matching of the horoscope should be done for marital happiness and bliss. The chances of marriage are after the 25th year of birth.
