In your horoscope, we see that Mars rules the 7th house which is the prime house of marriage. Mars is debilitated which is not good. Venus which is the karka for marriage is conjoined with Ketu in the bhagyastan. Your horoscope is weak on the marriage front. Marriage should be done after proper matching of the horoscopes, else possibility of separation is very much there.
Doing remedies of Venus and Mars will certainly help.
