Competing Kin Investment
Competing kin investment is the evolutionary account of in-law friction: a mother and a wife both have a real stake in the same man's time, resources and children, but their genetic and social interests in his life don't fully overlap — especially around 'his' family's line of grandchildren versus 'hers.' Daly and Perry frame in-laws as true kin through shared descendants (the basis of real cooperation), while empirical work finds conflict concentrated where those competing stakes are highest.
SEE THE PRACTICE
Turn a thought this research explains into one clear move.
THE THOUGHT
“She'll never think I'm good enough for him”
YOUR RECORDED RESPONSE
“I'm not auditioning for a place I already occupy in his life.”
ONE PRIVATE MOVE
Before the next visit, write down three true things about yourself that have nothing to do with her opinion of you. Reread them once in private the morning you see her.
How it sounds in your head
The inner script: 'She wants him spending Sundays with her — this is a tug-of-war I'm supposed to win.' The evolutionary account doesn't excuse the behavior, but it explains why the pull exists on both sides rather than being one woman's personal failing.
