After reading your 'missing out' concern, I would stick with a Nepali girl especially since you like to live like your dad and uncles. Every next generation people become more modern/open or far reaching (for better or for worse).

I am certainly not saying there is anything wrong with trying to follow your dad's footstep. That's just your choice. Philosophically understanding the big picture is one thing, but living the day to day life is different and can make you miserable. Even if you are rushing to meet the god, but there is a pebble in your shoes you'll have to stop and remedy the situation. You'll have to pass on God this time.

If festivities, food, her teej brata are that important for you; man don't do it. This life will feel tooo long.

And I commend you for pondering on these early enough. Like rewire said not everything is for everyone.

Goodluck!
