A marriage astrologer can explain everything about your marriage through your kundli. If Venus is weak or afflicted in the birth chart, it may give married life problems to an individual. If Seventh house Lord is in the bad house or afflicted with malefic planets, the person ceases to live happily married lives. The planets Venus and Jupiter are the karakas of marriage, and if they are in a good position in the horoscope, the person enjoys a happy married life.
