Imagine this: your ex—who cheated on you for years—calls you up, not to apologize, but to ask for money. Not for your shared kids, but to throw birthday parties for his stepkids. Yep, the children he has with the woman he left you for.
That’s the jaw-dropping dilemma one Redditor, a 32-year-old mom, faced when her ex demanded she pay a “lump sum” so his stepchildren wouldn’t feel left out while she throws long-overdue birthday parties for her children. The internet quickly lit up with takes hotter than a July piñata.
Was she selfish to say no—or was he completely out of line? Let’s unwrap this party-sized custody clash.

This story’s got more nerve than a kid begging for extra cake! Here’s the original Reddit post:







After pandemic-era birthday cancellations, she promised her 11-year-old daughter and 8-year-old son they’d finally get the celebrations they missed. Her ex—who pays child support and shares custody—suddenly asked her to chip in for three parties. For his stepkids. When she declined, he called her heartless and accused her of “dividing the family.”
Let’s be clear: parties are a want, not a need, and child support is for shared children—not bonus kids from a new marriage. The mom’s refusal to bankroll a party for kids she didn’t help create, especially when she’s receiving child support (not paying it), is financially and ethically sound.
In fact, family therapist Dr. Lisa Blum explains, “Ex-spouses often project guilt or financial stress onto the other parent. Clear boundaries prevent long-term resentment”. And according to a 2023 Journal of Family Issues study, over 65% of co-parents struggle with financial disputes after divorce—especially when stepfamilies are involved.
Her ex’s demand? It’s less about “family unity” and more about shifting financial pressure onto someone else.
Reddit’s throwing shade louder than kids at a bounce house!

Most agree she’s not the AH—she has no obligation to support the stepkids of the man who cheated on her.




Others commenters agree she’s not the asshole—her ex’s demand is entitled, backwards, and completely misunderstands how child support works.





Reddit is roasting this ex hard—calling his request outrageous, delusional, and downright laughable




Are these comments cutting the cake or just tossing sprinkles? You decide!
At the end of the day, this isn’t about cake or balloons. It’s about boundaries. This mom made a loving gesture to make up for lost time with her kids. Her ex tried to twist that into a shared financial obligation for kids who aren’t hers—and Reddit wasn’t buying it.
So, what do you think? Was she right to say no, or should she have chipped in “for the sake of the family”? Would you fund your ex’s stepkids’ birthday parties? Sound off with your take—we’re all ears (and maybe cake).
