Fear of ending up with a theist

I am an atheist unfortunately born in a family with both hindu and christians, and I happen to live in the most atheist friendly city in India enjoying my beef and pork together.

But I've noticed a stark decline in new atheists here, and the dating pool for me is shrinking too.

Almost 95% women I speak to are staunch hindu and muslims here, and that's an obvious dealbreaker.

There are the obvious "spiritual" and "agnostic" people but they are just closeted liberal hindus.

This is getting out of hand for me now as I plan to get into a relationship and figure my life out but, there's just no women left for it.

I just can't wrap my head around the fact that I may have to be a closeted atheist while my trad sherni does patriarchal pujas around the home.

How do I even go about this ? Because I also don't want to die alone, I definitely plan to marry, but also don't want a hindu/muslim partner but that's the entire population here nowadays.

Edit : I have already dated the trinity of hindu, muslim and sikh while staying closeted, and I CANNOT go through that again
