Looking at your horoscope we see that your ascendant is Pisces and Rashi is Tula or Libra. You are born under the Vishakha Nakshatra. Yes your 7th house which is the prime house of marriage and marital happiness is weak. Mercury which is the 7th lord is combust and retrograde. Jupiter which is the karka for husband is in the 12th house, which is not a good position for it to be. Possibility of separation is very much there in the horoscope.
