AITA for not assuming a grandparent role for some of my son’s kids, and refusing to pay for their college?
Money has a way of turning family gatherings into battlegrounds. One grandmother draws a firm line: she’ll fully fund college and even drop $100,000 toward a house downpayment—but only for Nancy, her biological granddaughter. The two children her son legally adopted from his second marriage? They’re on their own. She insists she never played the grandparent role with them, and distance—both literal and emotional—kept any real bond from forming.
Yet when she shares the generous plan with her son, his excitement spirals into demands for all three kids. What follows is a storm of accusations and veiled threats to sever Nancy’s access to her grandparents. The question lingers: does financial freedom trump the unspoken rules of blended-family loyalty?

‘AITA for not assuming a grandparent role for some of my son’s kids, and refusing to pay for their college?’
Everything starts with a crystal-clear boundary OP set long ago, one rooted in biology and emotional reality:

Life shifts dramatically when OP’s son enters a new chapter, bringing children from his second marriage into the fold:


Geographic miles soon mirror emotional ones, even as surface-level courtesy holds steady:


A sudden windfall catches everyone off guard, inflating expectations OP never intended to meet:


The confrontation erupts the moment imagined generosity collides with cold reality:



First, OP holds absolute legal and financial autonomy. No statute forces grandparents to bankroll education, biological or otherwise. Yet autonomy doesn’t shield anyone from emotional fallout. Dr. John Gottman, renowned family-systems researcher, warns: “When money publicly discriminates within blended families, it carves rifts that span generations.” (Source: The Seven Principles for Making Marriage Work, 2015). OP inadvertently positions Nancy as the prize in a power struggle between parents and grandparents.
Second, the son falls into the trap of assumed entitlement. He presumes newfound wealth automatically extends obligations to his expanded household—a common but baseless leap. Still, his outrage carries weight: legal adoption transforms those children into his own, morally and juridically. Rejecting them feels like rejecting his fatherhood.
A practical path forward? Establish a fixed education pool divided equally among all three, or route indirect aid through the son (annual transfers he manages). This preserves fairness without mandating fake affection. Crucially, OP should speak directly with Nancy—clarify the decision isn’t aimed at her—and place funds in an irrevocable trust beyond parental reach. Ultimately, love can’t be purchased, but it can certainly be lost over dollars.
These are the responses from Reddit users:
Reddit erupts in a kaleidoscope of emotions, from fierce defense of personal wealth to raw tales of exclusion that leave readers choked up.
Plenty of Redditors rally behind OP, stressing that money is a personal choice and bonds were never forged:















Sharp critiques slam OP, arguing the “blood only” mindset inflicts lasting wounds and self-fulfills distance:


















Heart-wrenching personal stories choke readers with the agony of exclusion in blended families:















A handful of balanced or lightly humorous takes push for pragmatic fixes over all-or-nothing fights:
















In the end, OP wields full control over her purse strings, yet that power extracts a steep toll: fractured ties and innocent children caught in the crossfire. Whether clinging to “blood only” or opening arms to a blended brood, consequences remain stark—only the bearers of pain differ.
What about you? Would you fund all three equally, reserve support for biology alone, or carve a middle path? And crucially: should family be measured by DNA or by daily effort?
