In your horoscope you have ketu and Jupiter conjoined forming the Guru Chandla dosha. Guru or Brihaspati is the karka for husband, this dosha forming in the 7th house is not good for marital relationship. Moon which is the 7th lord as Cancer sign is in 7th house, is debilitated in Navamsha. Your marriage house and its lord is weak and therefore proper matching should be done before marriage.
You should do fasting on Thursdays and also Recite Brihaspathi Mantra for benefits.
