Looking at your Birth Chart we see that Jupiter which is the 7th house lord is in the 12th house, which is not good along with Venus which is the karka for marriage. Saturn in the 7th house is likely to bring obstacles and delay in marriage. Ketu aspects 7th house from 3rd house, therefore your initiatives will not bring you the desires results. Also note you have strong mangal dosha and marriage should be with mangalik only. You are presently in the mahadasha of Ketu. The chances of marriage are very much in 2016.
