Saving for a house is hard enough without your own family treating your bank account like a shared resource.

One man moved back home specifically to save for a down payment, agreeing to cover half his mom’s mortgage while working roughly sixty hours a week across two jobs.

His sister, meanwhile, couldn’t manage to hold her own finances together, leaving her son to live with their mom while she racked up bankruptcies and unpaid bills.

When their mom started asking him for extra grocery money instead of asking the sister who actually caused the strain, he finally said no.

That single word turned into a much bigger argument about fairness and responsibility.

AITA for not wanting to give my mom more money?

I moved back home to save money for a down payment on a home. Me and my mom agreed that I’d pay half of her mortgage for rent.

Her mortgage is like $620, and I give her $380 a month.

This man works hard to afford the money, but his sister’s work ethic isn’t near as good.

I have 2 jobs, to where I pretty much work 13 hours a day 4 days a week and then 3 hours a day the other 3 days a week, totaling around 60 hours a week.

My sister is a deadbeat parent who can’t take care of her son, so he lives with my mom also, and he’s 12.

He also doesn’t really trust his mother to handle her finances responsibly.

My mom somewhat retired early but isn’t collecting social security yet, she’s pulling a small amount a month from a retirement account.

My mom doesn’t make the best financial decisions and ended up getting my sister a car, knowing she hardly pays her bills, filed for bankruptcy in the past, and has credit cards going to collections (we know this because my sister’s too lazy to change her mailing address).

I’ve paid my mom on time every month for the past 3 years. I hardly eat at home because I eat out at lunch during the day.

He’s starting to reach a limit for how much financial help he’s willing to provide.

Am I an AH because I don’t want to give my mom more money for groceries when my mom is taking care of my sister’s kid, which she contributes nothing to?

My mom will ask me for more money but not ask my sister.

Sounds like he’s right to finally recognize this boundary.

What did Reddit think?

This user brings up the topic of child support.

This commenter thinks maybe his mother has a point.

Maybe it’s possible for the family to get more support using other means.

Sometimes you have to tolerate unfair situations.

At the end of the day, he’s the reliable one, and the reliable ones get exploited the longest.

Paying rent on time for three years while working sixty hours a week earns you exactly zero credit in a household where accountability only flows one direction.

His mom didn’t ask the sister for extra grocery money because the sister would’ve said no without a shred of guilt.

He, on the other hand, has said yes for years, which taught everyone he’d keep saying yes.

Refusing once isn’t selfish, it’s the first honest answer he’s given in a long time.
