In your horoscope, Moon rules the 7th house which is the house of spouse, marriage and marital life. Moon is in the lagan in the Uttarashadha Nakshatra of Sun. Sun rules the 8th house which is the malefic house in your chart. 12th lord Jupiter is in the 7th house and exalted which is not good. Venus the karka for marriage is also in the state of infancy. Your 7th house, its lord and karka are all weak, hence you will face marriage related problems. There will be delays in marriage as things on the relationship front will not go as plan.
Marriage can only be there if you are willing to make adjustments and want to move ahead in life. You can do fast on Mondays.
