AITAH for getting angry at my soon to be ex husband for not spending his birthday with me and our kids?

A soon-to-be ex-husband skipped out on the birthday celebration his family had planned and the kids were buzzing about, all because his brother dangled a last-minute invite. He left four young children crushed and waiting. She’d pulled together a full day despite their tight budget and upcoming amicable divorce: park visit, lunch at his favorite spot, backyard camping, his favorite dinner, and fireworks.

Days earlier, his flaky brother called with an outing the kids couldn’t really join, and he lit up, agreeing instantly while talking about it loud enough to sting their oldest. On the big morning, he vanished before the excited crew could even shout “Happy Birthday Daddy!” Is she wrong to be livid, or does “his day” give him a total pass—even when it breaks his kids’ hearts?

‘AITAH for getting angry at my soon to be ex husband for not spending his birthday with me and our kids?’

It all kicked off after they agreed to an amicable divorce at year’s end, still aiming to co-parent smoothly and keep their long friendship alive:

Just days before the birthday, his brother famous for canceling unless there’s something in it for him called with an invite, and he got thrilled and said yes even though it wasn’t kid-friendly:

The quick four-minute call, a promise to be back by 2 p.m., then texts pushing it later crushed the kids even more:

This whole mess boils down to a dad picking a spur-of-the-moment hangout over the birthday plans he’d helped shape with his own kids. In the middle of a pending divorce, quietly leaving the house and pushing back his return time multiple times did serious emotional damage to children who were already excited and vulnerable.

Some might argue it’s his birthday, so he deserves to call the shots—especially when marriage stress is piling up. The brother’s call offered an easy escape, and taking it could just be him grabbing a rare bit of fun. But the real problem is he’d already committed to the family day and even insisted the kids be included.

Society tends to hold parents accountable for putting children first, particularly dads with young ones who soak up every signal about where they stand. Behaviors like this can point to the detachment phase many go through during separation, mentally checking out to ease into solo life.

Relationship expert John Gottman has pointed out that broken promises on meaningful days can shake a child’s sense of security and trust in parents (The Gottman Institute). Moving forward, the mom might protect the kids best by lowering expectations around dad’s involvement and letting him drive any future plans. He could start repairing things with a straightforward apology to the children and reliable actions afterward. Co-parenting counseling sooner rather than later would help both set clear boundaries and avoid more heartbreak down the line.

Here’s what Redditors had to say:

Folks online didn’t hold back, with most rallying behind the mom and aching for those poor kids:

Plenty straight-up called out the dad’s actions as revealing his true priorities:

Others went tougher, telling her to quit bending over backward and prepare for single parenting:

A handful suggested stepping back entirely since divorce is on the horizon:

Some stayed on the fence, mostly just feeling bad for the little ones:

A day that was supposed to be full of family fun turned into one of disappointment and tears, with the young kids feeling pushed aside on what should have been a shared celebration. While parents absolutely deserve some personal time—even on their birthdays—repeatedly breaking promises to excited children, especially amid a divorce, can leave scars on their sense of security and trust in dad.

What’s your take: When there are little kids involved, should a parent’s birthday always include them, or is it fair for the adult to go fully solo? Does this sound like a one-off bad choice, or a warning sign for tougher co-parenting days ahead? Share your thoughts in the comments!
