AITA for feeling like it’s not my job to make sure all the kids at my ex’s house have just as much as our two sons?
A devoted dad is under fire from his ex-girlfriend and her new husband, who expect him to foot the bill for their stepdaughter and baby’s experiences to “level the playing field” with his two sons. From summer camps to field trips, they argue he should ensure all kids in their household have equal opportunities. He firmly refuses, insisting his responsibility begins and ends with his own children, sparking heated disputes and even a failed attempt to sue for child support.
This isn’t just about money—it’s about boundaries, fairness, and the complexities of blended families. With Reddit weighing in with strong opinions, let’s break down this drama and explore whether this dad’s hardline stance is justified or if he’s being too rigid in a tough situation.

‘AITA for feeling like it’s not my job to make sure all the kids at my ex’s house have just as much as our two sons?’
OP’s Background:

Financial Adjustments in Co-Parenting:


Pressure from Ex and Her Husband:


Demands to Support Ex’s Other Kids:


OP’s Firm Refusal:


Ongoing Tensions and Legal Pushback:


Co-parenting after a breakup is a delicate balance, and OP’s situation highlights the challenges of maintaining clear boundaries in a blended family. By covering all medical and dental expenses for his two sons, OP has already gone beyond the original 50-50 agreement, easing his ex’s financial burden. Yet, her and her husband’s expectation that he should fund their stepdaughter and baby’s experiences—like summer camps or field trips—is unreasonable and oversteps his responsibilities.
Psychologically, the ex and her husband may feel pressure to create equality in their household, especially with another child on the way. But as Dr. Philip A. Cowan, a family psychology expert, notes, “Clear delineation of financial and emotional responsibilities in blended families is key to preventing conflict” (Family Process Journal, 2019). OP has no legal or moral obligation to support children who aren’t his, especially when the ex’s husband is equally responsible for their family’s financial planning.
Reddit’s advice leans heavily on documentation and boundary-setting. Many suggest OP continue using Our Family Wizard to keep communication professional and trackable, especially given the ex’s attempt to pursue child support. The husband’s audacity in demanding OP fund his kids raises concerns about entitlement and potential instability in their household, which OP could use to strengthen his case if tensions escalate legally.
OP’s best move is to stay firm, keep interactions on the app, and consult a lawyer if the pressure persists. While helping the other kids might seem kind, it risks setting a precedent for endless demands. Prioritizing his sons’ stability and maintaining clear boundaries will serve everyone best in the long run.
Here’s what the community had to contribute:
Reddit didn’t hold back, with most users firmly backing OP and slamming the ex and her husband for their entitled demands. The comments range from supportive to snarky, with practical advice mixed in. Here’s a breakdown:
