Divorce means break up of a marriage or a serious relationship. It can be surely studied through a birth chart by an astrologer. I don’t understand why you said it is not possible for Indian astrology to predict break up of a marriage (divorce). If separative planets are strong will lead to divorce.
Even if the match making is done before marriage by experts in astrology, if an individual’s birth chart shows two marriage or a break up of first marriage it will happen.
Dear Hema everything will get fine as you expected. All Best wishes.
