Most people who asks this questions, are true lovers. It means you love him and he don’t care or you don’t know he will marry you or not. But astrology have the answer. Just open the horoscope of your partner and let’s analyze if he will marry you or not.
Jupiter is known for honesty and justice and Rahu is the dishonesty and injustice. Both planets are opposite to each other.
Jupiter is only planet who encourage you to speak the truth, to fulfill the promises and to keep patience in relationship. Jupiter gives discretion so keep your faith in relationship. Jupiter is the only planet who bless you with caring nature. For all good qualities in a person, Jupiter is responsible. If Jupiter is strong in your horoscope, you will be able to prove your words. If its not good in your horoscope, you will remain in compulsion.
On the other hand, Rahu make the people clever. Especially if your Rahu is in Ascendant or 5, 9th house of your horoscope, you do the promises and the time of action you will give the reason. Rahu always generates the reasons. Rahu lies like truth.
If the Jupiter in your partner’s horoscope, sitting with Rahu, he will not be able to marry you because he is helpless. If Jupiter is alone anywhere in the horoscope, you will be owner of your own free will. You cannot escape, cannot cheat and cannot break the promises.
