Mom Wants to Put Son’s Girlfriend on a Budget as She Overspends on Groceries. Now He’s ‘Offended’ and Says Mom ‘Embarrassed’ Her

A woman is wondering if she overstepped by putting a spending limit on the meals her adult son’s girlfriend cooks for their household.

In a post on the AITA subreddit, the original poster (OP) explained that her 23-year-old son moved back home after graduating from university in June and landing a job nearby. He’s been in a long-distance relationship with his 21-year-old girlfriend, Carmella.

Back in October, Carmella — who had taken a semester off and was living with her mother — decided she didn’t want to return to college. According to OP, Carmella’s mother told her that if she wasn’t going back to school, she’d need to move out, which left the young woman with nowhere to stay.

OP’s son is scheduled to move into his own place in January and had already invited Carmella to move in with him then, suggesting she could find work in the area. But because Carmella needed somewhere to go sooner, the couple asked if she could stay with OP in the meantime.

OP agreed.

She added that she isn’t charging either of them rent. Her only conditions were that they clean up after themselves and show respect in the home, which they accepted.

After Halloween, Carmella moved in, and OP said she has “been a joy to have around.” Carmella is still job hunting, and as a way of contributing, she frequently offers to cook dinner for the family. OP said she has repeatedly told her it wasn’t necessary, but Carmella insists — and since she’s a good cook, OP has let her go ahead.

About a week into this arrangement, Carmella asked to make a particular dish and needed ingredients they didn’t have. OP offered her her card so she could grab what was needed.

“Since then, it’s become a regular thing,” OP wrote. At first, she didn’t mind because Carmella would also pick up OP’s usual groceries, and it seemed like a fair trade.

However, after a couple of weeks, Carmella began making multiple trips to the store each week and buying items that wouldn’t normally fit into OP’s standard food budget — things like steak and seafood.

OP said she asked Carmella on a Sunday shopping trip to please get everything she would need for the week in one go. Carmella agreed, and OP thought that would resolve the issue.

The next night, after the family finished dinner, OP overheard Carmella talking with her son. Carmella mentioned wanting to make steak later in the week, and when her son agreed, she said she’d need to go back to the store for more ingredients.

“My son turns to me and says, ‘Mom, give her the card,’” OP recalled.

This time, OP refused. She reminded them that she had already given Carmella money for groceries on Sunday and had specifically asked her to get everything she needed then. OP also explained that feeding six people steak just wasn’t in the budget right now, though she suggested she might serve it as a special meal for Christmas dinner instead.

OP then added that if Carmella wanted to keep cooking for the family — which she does appreciate — she would need to stick to a set budget going forward, and apologized for not putting that boundary in place earlier.

According to OP, Carmella looked upset and her son seemed offended.

Later, her son told her she had “embarrassed” Carmella when the younger woman was simply trying to do something nice. OP responded that while she values Carmella’s effort, the groceries are still being purchased with her money, and she simply can’t afford frequent high-end dinners. She also pointed out that her son is welcome to give Carmella his own money for these meals if it matters that much to him.

Her son argued that they would only be staying “a few more weeks” and asked why she couldn’t just keep his “guest” happy during that time.

In response, OP emphasized that neither he nor Carmella are really guests anymore. They’re living in the house as family, not as short-term visitors, and that comes with different expectations — including respecting the household budget.

At the end of her post, OP asked if she was wrong for imposing a spending limit on her son’s girlfriend.

Most commenters felt she was not in the wrong.

One person pointed out that Carmella likely wasn’t trying to exploit the situation but may not have much experience managing a food budget for a six-person household. They suggested that while she might feel embarrassed now, she’ll hopefully recognize that the discomfort comes from her own lack of awareness rather than OP’s boundary.

Others agreed with OP’s stance on her son, noting that if he wants restaurant-style dinners and expensive ingredients, he should be contributing financially — especially since he and Carmella are effectively part of the household, not visiting guests.
