Looking at your horoscope we see that Mars is lord of the 7th house which is the prime house of marriage. Mars is debilitated in the natal chart which is not good. Debilitated Rahu aspects the 7th lord Mars. You are also in the mahadasha of Venus and antardasha of Rahu, therefore this period is not good for relationship as well. Marriage chances are strong after August 2017. Matching of the horoscope should be done for marital happiness.
