We can only check compatibility between horoscopes of the boy and girl. We cannot say whether the marriage will be possible or not and whether it will happen or not. For e.g there will be many girls whose horoscopes match with the most eligible bachelor Rahul Gandhi, but it does not mean that he will marry all of them. That depends on various other factors. Please do not think Astrology can predict your future with certainty. If it were possible, there will be no charm in life.
