Whatever has happened has nothing to do with your Venus Navamsa. Sun, Moon and Venus are the weakest planets in your horoscope and they are malefics too. You could get married before mid 2018 and your marital life will be blissful. However you will have monetary problems in life since your earnings will not be in proportion to your work done. Try to get married to a working girl. Now that you have learned a lesson, do not go after rich father in laws.
