Upon examining both birth charts, it is observed that the boy is born under Vishakha Nakshatra (4th Pada/Charan), while the girl is born under Rohini Nakshatra (3rd Pada/Charan). Your ashtakoot guna milan score is 13.5 which is less than 18 that is required for marriage. There is Nadi dosha and also Gana dosha as boy belongs to Rakshasa Gana.
Nadi Dosha analysis
According to the traditional principles of Ashtakoota Guna Milan, both these Nakshatras belong to Antya (Kapha) Nadi. Since the prospective bride and groom have the same Nadi, this results in the formation of Antya Nadi Dosha, and consequently 0 out of 8 points are awarded in the Nadi Koota during horoscope matching.
Nadi Koota is considered one of the most significant components of Kundli Milan because it is traditionally associated with health, compatibility, family harmony, and the well-being of future children. When Nadi dosha is present, there is an imbalance in constitutional energies (Doshas), which is believed to increase the possibility of divorce, health concerns, or difficulties related to childbirth. It is very important to check if your Nadi dosha gets cancelled.
Also as there is Gana dosha and your grahmaitri score is just 1 out of 5, you should check its cancellation as well. Gana is basically temperament issues and when Gana dosha is coming it means arguments, misunderstanding and conflicts.
It is best to get GRAHA Milan done. A Graha Milan is complete horoscope matching which checks Nadi dosha cancellation, Gana Dosha cancellation, and checks the 7th house, lord, and karka in the horoscope of boy and girl. It also checks for divorce yog if at all in any horoscope.
A detailed analysis will only help you find answers to all your questions.
