I got married one year back. Our kundalis didn't match and we were only good frnds. Then we took an initiative to marry each other because we knew the basic nature of each other. Only 13 gunas matched but still we are too happy and blessed. We hardly had a tiff. On the other hand I know a couple whose 32 gunas matched and still they took a divorce. Astrology is a science but nothing is more important than understanding and trust. So if you believe in yourself, no astrology can challenge you.
