Looking at your birth chart it is see that Saturn rules the 7th house of marriage, which is the prime house for marriage and marital life. Saturn is the 8th lord and hence the most malefic planet in your horoscope. Saturn is posited in the 4th house which is for family comforts and aspect by Rahu. Your 7th lord Saturn is badly afflicted in the horoscope. You are presently in the mahadasha of Jupiter and antardasha of Ketu, The period after August 2015 can bring you second marriage, however it would be important that you are willing to put efforts in finding the alliance.
