Should I Cut Off My Mom Financially After She Used My Money for Siblings Wedding?

A 29-year-old woman is about to find out how fast family support can turn into a financial betrayal. She’s been saving for a down payment, quietly doing the responsible thing while still helping her mom out with household expenses and emergencies.

Then the truth slips out through a conversation with her sibling: her mom used a big chunk of the money OP gave her to pay for an extravagant wedding. No warning, no discussion, just a switch from “we’ll get through it together” to “your savings funded the dream.”

Now OP is stuck between staying peaceful and protecting her future, and the wedding money is sitting in the middle like a live wire.

Original Post

I (29F) have always had a close relationship with my mom, who has been a single parent since my dad passed away when I was a teenager. Over the years, I've worked hard and managed to save a significant amount of money, some of which I have shared with my mom for household expenses and emergencies.

Recently, I found out through a slip in conversation with my sibling that my mom used a large portion of the money I gave her to fund my sibling's extravagant dream wedding. This was never discussed with me, and I felt betrayed that she would use my hard-earned savings for something so significant without even mentioning it to me.

For background, I have been saving up for a down payment on a house, and every dollar counts towards my goal. Knowing that my mom took advantage of my financial support in this way has left me feeling hurt and taken advantage of.

I understand that family is important, but I can't help feeling like my mom prioritized my sibling's desires over my future financial stability. I haven't confronted her about this yet because I'm afraid it will lead to a huge argument, but I can't ignore the resentment building up inside me.

I'm torn between wanting to maintain the peace within the family and standing up for myself and my financial boundaries. Would I be the a*****e if I decided to cut off my mom financially as a way to protect myself and my future financial goals, even if it causes tension within the family?

So, WIBTA?

This is similar to the AITA conflict where someone refused to financially support their parents after they disowned their sibling for coming out as non-binary.

When OP realizes her down-payment money got rerouted into her sibling’s “extravagant dream wedding,” the trust she built with her mom starts to crack.

The fact that her mom used the money without telling her, while OP was still counting every dollar for her house, makes the betrayal feel personal, not just financial.

Every time OP imagines confronting her mom, she can already hear the “huge argument” coming, especially since her sibling is part of the fallout.

That’s why OP is weighing cutting off financial support, not to punish anyone, but to stop her mom from doing this again with her hard-earned savings.

If OP keeps funding the wedding lifestyle, her house dream is the one that will keep getting postponed.
