Your 7th house which is the prime house of spouse is ruled by Mars as Aries sign is there. Mars is in the 11th house of gains with Venus, which is never good. Both planets are conjoined with Mercury which is the 12th lord and have aspect of Rahu. Rahu aspects the 7th house as well. Your 7th house and 7th lord of marriage is weak and marriage should be done after proper matching of the horoscope for marital bliss, else chances of separation are very much there in your chart.
