Sub continent? What is that? Are we talking about mermaids?

And what does it matter why someone doesn't marry? Live your own life and find someone who is available and a good match.

As for the question... that was asked not that long ago too, either by you or someone else.
A number of people -incl me- said that in a country with arranged marriage they are likely happy to be free from the burden of having to get married. In such countries women usually are still expected to be subservient to their husband. Why voluntarily go there again? I wouldn't.
And if it was a marriage of love then people need time to heal from the loss.
