I can see the logic. The realities of day to day life and managing a household together are a considerably larger presence than most people realize until they’re shoulder deep into adult life.

For context, see research by Myers, D., 1993 (which I can’t find a link to at the moment) about differences in satisfaction in couples in India in arranged marriages and couples in Amerikkka in marriages of choice, and compare it with the later research Myers, 2005.

More specifically to your statement about auntie zeroing in on something, see MacDonald & Ross, 1999.
