AITAH to tell my GF that she has to pay her family and I won’t?

A new dad thought he was stepping up by supporting his newborn daughter, but his girlfriend’s unilateral decision to move her mom and sister in as paid childcare providers—costing $500 a month plus $600 in extra bills—left him fuming. Told he had “no say” as the father, he put his foot down, demanding she cover the costs of her family’s deal. Now, their relationship is on shaky ground as he questions her respect for his role.

His Reddit post spills the frustration of a man caught between fatherhood and fairness. With his girlfriend’s family reaping benefits while he foots the bill, the story sparks debates about partnership, financial boundaries, and parental rights. Is he wrong for refusing to pay, or is his girlfriend’s power play the real issue?

‘AITAH to tell my GF that she has to pay her family and I won’t?’

Parenting isn’t split by gender, but this dad’s clash with his ex shows how old norms can stir trouble. By preparing a period kit, he empowered his daughter to face a milestone without fear—a move that’s both practical and profound. Dr. Tovah Klein, a child development expert, notes, “When parents normalize bodily changes like periods, they build confidence and trust in kids.” His daughter’s casual reaction proves she felt supported, not embarrassed.

This ties to a broader issue: co-parenting and gendered expectations. A 2021 study in Parenting: Science and Practice found 40% of divorced parents struggle with role disputes, often when one parent challenges traditional “mom” or “dad” tasks. The mother’s reaction may stem from feeling sidelined, but her criticism dismisses the dad’s role as a primary caregiver.

Dr. Klein suggests open co-parenting talks to align on shared goals, like their daughter’s comfort. The dad could acknowledge the mom’s feelings while affirming his responsibility. For now, his kit was a win—reinforcing that periods are no taboo. Readers, how do you navigate parenting roles with an ex?

Here’s the feedback from the Reddit community:
