Looking at your natal chart we see that Jupiter rules the 7th house of marriage. Jupiter is aspected by Rahu which is in the 7th house of marriage. Rahu in the 7th house of marriage is never auspicious. Venus the karka for marriage and love is debilitated in the Navamsha chart. Your horoscope is weak on the marriage front, which can bring delay, obstacles in marital life. Marriage should be done after proper matching of the horoscopes for a happy marriage. The possibility of love marriage is there in your chart, however like I said there will be lots of obstacles and problems before.
