Looking at your horoscope we see that your 7th house which is the prime house of marriage is ruled by Venus. Venus is posited in the 7th house in the krittika nakshatra which is the Nakshtra of Sun. You are presently in the mahadasha of Jupiter and the antardasha of Venus. Strong period for marriage stars after September 2016 when Jupiter the karka for husband enters Virgo. You should keep trying now and going forward you can expect good results on this front.
As I can see your ascendant is Cancer and its lord Moon is in the 8th house which is not good. 7th house is ruled by Saturn and Saturn is posited in the 6th house, which is also not good. Venus the karka for marriage is combust. Rahu is posited in the 7th house forming the Kalathra Dosha. There are certainly obstacles on the marriage front and marriage should be done after proper matching of the Horoscopes.
The chances of marriage are in 2017. Doing the remedies of Saturn and Rahu are very important to avoid delays.
