Hello Dude, it was the same issue with my friend as well. He wears Janai and worships daily. He married to the Adhikari girl happily and her cousins were Adhikari too. It happens..Take it easy. Put the faith on your relationship not on your cast type. Haven't you watched Lageraho Munna bhai? If you believe in palmist and astrology; then I don't have to say anything. Introduce her to your family. The more you speak about her in your family; the more they will appreciate her easily.
