AIBU to tell my SIL not to comment on my finances?

I could really appreciate an outside perspective on an exchange I had with my SIL, because I genuinely can’t work out whether I’m being unreasonable or whether she crossed a line.

We’ve known each other for seven years and I have never really called her out on anything before. She can be quite bitchy, argumentative and judgemental, so normally I let things go, but this one didn’t sit right with me. For years she’s been like this with comments, she’s 26, works in a gym and has had no real education and has no respect for anyone besides her husband and 19 month old, oh and her parents. Not her in-laws. I am 37, married and work in corporate and grateful for my role.

I went to visit my family yesterday and I tend to travel around on foot (I am London based, learning to drive). She essentially interrogated me on text about when I was going to pass my driving.

THEN..

She sent me a voice note yesterday randomly saying “I wanted to ask you, those Bad Bunny tickets weren’t cheap. My cousin told me how much you paid. That isn’t saving.” She also sent a load of shocked/laughing emojis and seemed genuinely surprised that I had spent £120 on the ticket.

My immediate reaction was basically, wait, did she actually just say that? I questioned why what I had spent was even being discussed between her and my cousin. Her response was, “I didn’t know it was a secret.” That completely missed my point. It wasn’t a secret as the ticket prices are online. What bothered me was that my spending had apparently been discussed and then she had taken that information and made the judgement, “That isn’t saving.”

I told her I would appreciate it if my finances weren’t discussed or commented on because ultimately they’re personal and don’t really have anything to do with her.

She replied: “I commented as a caring joke to you. Not to anyone else because I know you want to move. You do you. If you took offence to what I said, I’ll be careful in what we speak about in future.”

I then sent her a voice note because I genuinely didn’t want it to become an argument or create unnecessary drama. I explained that I wasn’t offended. I was simply saying that the comment didn’t make sense to me because she doesn’t actually know my financial situation. She doesn’t know my salary, what I save each month, what my husband and I save together or how we manage our money.

I also said that I respect her enough not to question what she earns, how much she saves, what she spends her money on or how she and her partner manage their finances, and I’d just like the same respect back.

I also mentioned that maybe part of it is where I am in life now. I am 36, married, work in a corporate environment and I have just become a lot more private about certain things as I have got older, especially finances. I work hard, I save, but I also enjoy my money when I choose to.

I wasn’t saying that being 36 somehow makes me superior to her because she’s 27. I was trying to explain that I am settled in what I consider a personal boundary. She’s private about certain areas of her own life too, which I’ve always respected. Her response was: “Don’t use the age line with me.” She then started saying things like: “I didn’t say that. I didn’t question how much you earn. I didn’t question this or that.” She seemed to reframe her original comment as though all she had jokingly said was, “Bitch, you should be saving.”

But that wasn’t really what I was responding to. Her original comment was specifically that she’d heard how much I’d spent on the tickets and that “that isn’t saving.” Throughout the conversation she also kept coming back to the idea that I was offended. She repeatedly said, “I didn’t mean to offend you,” and later, “You’re clearly offended.” That’s probably the part that has confused me most, because I don’t personally see being offended and setting a boundary as the same thing.

From my perspective, I wasn’t saying, “How dare you say that to me?” I was saying, “That assumption isn’t correct because you don’t know my finances, and I’d rather you didn’t comment on them.”

She also started explaining that what she’d said came from a place of caring and brought up personal things I’d previously confided in her about, including the stress of living with in-laws (me and husband are gearing towards a move) and difficulties I’ve had with my living situation.

That made me uncomfortable because I couldn’t really understand what those things had to do with whether spending £120 on a concert ticket means I am or am not saving money. Her face has changed a lot since I met her, and I know it’s all fillers and hair injections, but I don’t care! That is where her money goes, you do you 😂

I’m genuinely curious how this comes across to someone completely outside the situation. Was I reasonable to say I didn’t want comments made about my finances? And does correcting somebody or setting a boundary automatically mean you were “offended”?

She is unreal in the worse way. She also threw a dig to the fact she has a child sleeping and needed to sleep, they will be waking up in the night. Fully knowing me and my husband are childless (I don’t let in how much me and my husband wish to be parents). But I hope I offended her because she needs to be bought back down. I am constantly polite to her and she’s so lucky to have ME as a SIL.

It's Sunday afternoon. I'm a teacher. I came here for a little interaction and ended up feeling like I'm at work with teenage girls.

Chronological age gap or not, you both sound petty and ridiculous, and need to grow up. Being 37 I would have expected you to be the more mature, but nope.

"Well SHE did this!" Meh, so what?

As for the child thing and needing to sleep because they get up. That's just life with a child - not everything is a dig at you (thinking it is is another teenage trait).

And now I'm tense. 🤦🏼‍♀️

Edited

Telling someone to mind their business with their saving tips, isn’t grown up? And the other person reacting with ‘you do you’ .. that isn’t grown up lol. Sure.

Why do you keep mentioning her age? It makes you sound patronising. That and mentioning you job is 'corporate' and she works in a gym.
What exactly is your job that you look down on other people?

I don’t look down on others, just saying I don’t need her advise on saving tips and that ‘this isn’t saving’ is quite huge coming from someone on their parents money!

Don't be obtuse, if it was just that then obviously not. On either side.

But it wasn't. It was texts and voice notes and unnecessary drama, followed by ridiculous bleating about how fabulous you are, and how awful she is on here.

If I was her I'd be laughing at you and your absolutely silly superiority complex. Neither of you are better or worse than the other, you're just different. And that's OK.

You may want to reflect on why you've gone to such pains to convince a group of strangers of your apparent superiority.

you clearly did tell her you had to save. And the venom was on her parenting skills. Her face full of fillers, her job and lack of eduction and all the other horrible abuse you’ve hurled at her.

But you’re on your in-laws money, and are a decade older, you don’t have a home.

YOU'RE on someone else's parents' money though...

Paying bills doesn't change the fact that you live in someone else's house.

Simonjt · 13/09/2026 17:02

Unless you married a relative you have also married into the family.

I wouldn’t say anything, but if I knew a married 37 year old who wasn’t able to be independent I would have huge concerns about their finances and their ability to parent when they haven’t even be able to house themselves.

It looks like you do need professional advice regarding savings if you are unable to house yourself at 37 years old.

I wouldn't have replied. Don't feed the beast

You clearly do need some advice if you're paying for concert tickets and IVF while living with your alcoholic in-laws 😂

whippersnapper55 · 13/09/2026 17:13

Bloody hell, what a lot of drama 🙄 from her perspective, you're living with her parents, apparently saving to move out and yet spending £120 on concert tickets - I can see where she's coming from to be honest! It sounds like you've confided in her quite a lot so she probably didn't realise that your finances are off limits 🤷‍♀️

QuantumLevelActions · 13/09/2026 17:23

YWBU to bother answering her at all. That voice note was ridiculous.

Ignore her.

MorganKitten · 13/09/2026 17:24

You opened your post being demeaning about her, you went on about her age yet seem to be the one who needs to grow up. You are living with your in laws too so have no grounds to slate her on that. As the older maybe be more mature and not get into these conversations.

She’s not living with her parents. The two men are brothers, the sil is not her husbands sister.

How ironic that you belittle your SIL because she is 10 years younger than you, thinking yourself more mature when you have zero insight into your own behaviour nor the ability to reflect and realise that you are wrong and have been very unkind. I wouldn't even expect that from a 26 year old, never mind someone in their late 30s.

saraclara · 13/09/2026 17:33

What a load of long-winded nonsense...
In future, just ignore and don't feed the drama. You don't have to prove a point, it's ok to disengage.

All of that.

In a previous post you asked what you'd done that was immature. Responding to her and sending that long (and patronising) voice note was extremely immature. Maturity would have been either not responding at all, or a single massage saying that you can afford to save and also have the occasional treat.

LovelyLassie · 13/09/2026 17:33

I think you’re both as bad as each other. You clearly look down on her job and education. I also suspect the ticket price discussion between cousin and SIL was just a passing comment and they didn’t spend all evening analyzing your finances.

You should have simply failed to respond to her message, leaving her statement hanging and unresponded to. That would have said all you needed to have said. There was no need for things to spiral and both of you to tie yourself up in knots trying to explain. It’s got completely and disproportionately out of hand.

Surely the simplest response was, no response. Instead you're now in a tit for tat like a teenager, which given you are almost 40 and you and your husband live with his parents, she has a baby and lives with her parents but it sounds like not the baby's father, who still lives with his parents, sounds like about the right age range. All of you need to grow up.

BetterWithPockets · 13/09/2026 17:40

So she’s nosy, a rude person with an awful personality and apparently (for reasons you’ve not given) lucky to have you as a SIL…
You really don’t like her much, do you?

Chewbecca · 13/09/2026 17:40

Blimey, what an elaborate fuss over a chatty, off the cuff remark. You do sound like a petty, insecure teenager.

How are they as bad as each other. The woman simply commented on the cost of the tickets and saving. The op has run everything about her down,from her age, to her appearance, to her job, to her Education, to living situation, to her personality.

my take is the op is jealous of her, and insecure. So is taking the things she’s envious of and turning it on its head. She’s younger, a parent, doesn’t pay bills, likely attractive,

the op in comparison is staring at 4o, homeless,has to pay bills, sadly struggling to conceive and clearly can’t afford to move out.

Kokonimater · 13/09/2026 17:54

It seems that the truth is, even though you are in denial about it, that you were deeply offended and almost incensed with her audacity to question you or challenge you. And that is okay if that is how you felt but the emotionally intelligent thing to do would be to have not engaged with it, not tried to express or explain yourself just be the bigger person And let it drop.
As you say, you are 10 years older than her so you have the benefit of 10 years further wisdom. Maybe use that wisdom.
