Kindly note that Nadi Dosha is very Important. If Nadi score is 0 it is not good. However what you are looking at is only Guna Milan. Agreed that your Gun score is 14 , which is less than minimum. You need to check if the Dosha get cancelled Naturally. Many times the Dosha get cancelled that is why many people with less Gun milan have happy married life. you have not done the Graha Milan which is more important than Guna milan. You should read my articles on Complete Horoscope Matching.
