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.

Christ.
Imagine thinking you are winning at life and somehow doing better than someone a decade younger, while still living with parents, whether they are yours or your husbands.

The sneering tone towards her for making a passing comment about how expensive these tickets were. Yet, I qm prepared to bet that this was not the first salvo in the battle. It very much reads as a response to a previous comment from you.

Notrainingbutpouring · 13/09/2026 14:41

Maybe she’s frustrated that you are living with your in laws (her parents) which probably significantly impacts them and she’s hoping you’ll move quicker than your own set timeline. Are you paying rent to her parents/contributing to their household?

Op is not living with sil’s parents.

amyds2104 · 13/09/2026 16:20

I have to say you sound immature and such hard work! She was in the wrong for speaking to you about financial things as it’s not of her business but you sound equally unpleasant by your responses to her but also to people on here when they disagree with your approach. One small thing and it creates a massive argument. Sounds like an exhausting way to live.

hourspassed · 13/09/2026 16:19

Her 'you should be saving' comment hit a nerve with you. You keep mentioning your age and that you have a corporate job but you still live with DH parents?

To be honest, the whole thing sounds like some weird playground argument - a big old fuss about nothing - she said, she said. Why engage with it? If my SIL had sent me that message my response would have been to tell her to bugger off. End of conversation.

SilverTotoro · 13/09/2026 16:12

Honestly this is a mole hill - mountain territory. Her message was rude but to give this more head space than a quick eye roll and a thumbs up emoji is just feeding the drama.

Schoolchoicesucks · 13/09/2026 16:11

You keep saying "she is married into the family" as though you have a greater claim on them when you are both married in. YABU for that.
YABU too for leaving her sooo much detail via voice note. It's petty squabbling and point scoring. She may have thought you were closer confidantes than you do - that because you had shared with her about finding your MIL tough that you could tease one another like siblings do over where they spend their money. You don't like that, but you clearly judge her for spending her money on her appearance while living with her own parents.
If you don't like her, disengage.

KKD09 · 13/09/2026 15:23

Regardless of an offence or not, why is she giving someone 10 years older than her advice? Her husband is close in age and stil lives at home. It’s just boundaries, I don’t pry into her life and finances.

Why do you keep going on about the 10 year age gap if you don’t care it?! You both sound about 13.

I think it’s odd that neither couple live on their own. I wouldn’t comment on this but I would think it. Maybe she thinks you should move out asap and not spend money on concert tickets.

Sugarnspicenallthingsnaice · 13/09/2026 16:07

Oh so she's back to 26yo now.

I thought maybe you'd taken such a long time to type out that massive OP that she'd had a birthday before you finished it.

What about you, have you made your mind up how old you are yet?

DontyMon · 13/09/2026 16:06

KKD09 · 13/09/2026 16:03

I did say this, it was more ‘I can afford ticket and still save’

Again, the age thing was related to the way I like
keeping things private. It isn’t a huge deal

TBH it sounds like a massive big deal to you. Being reserved about money isn't anything to do with age. Surely you know that.

If you really wanted to keep things private, you would not even engage with this absolute drivel

But you started a thread on it, and have repeatedly commented on it.

powersthatbe · 13/09/2026 15:59

I think you could have shut the whole conversation down a lot quicker with “I earn enough to save and buy concert tickets”.

You had it in your hands to minimise the drama her comment brought to your door. Despite suggesting you are more mature than her, I would beg to differ.

None of her business - but I would have just ignored her message

This

a simple. “ eh? Why are you and xx talking about me ? Thats weird id never do that to you , my savings are fine no need to worry and NO more

KKD09 · 13/09/2026 15:45

Sorry, not independent, doesn’t pay bills at home or any contribution.

I do all of those at my in-laws. We are also paying for IVF, so that would go towards buying a home. Again, we don’t need to share that with my SIL/BIL.

I was replying to @alcovecupboards . I agree with you op.

Notsosweetcaroline · 13/09/2026 16:01

KKD09 · 13/09/2026 16:00

She owes me nothing. It was more so that I have become reserved and don’t need to explain my finances to a 26 year old, that’s between me and husband if anything.

Then stop telling her how you don’t like living there and need to save as you clearly have, you opened that door.

Livpool · 13/09/2026 16:01

bunnypenny · 13/09/2026 14:33

Christ how long was your voice note?

just ignore her or send a thumbs up FFS.

This! I wouldn’t have even responded.

DontyMon · 13/09/2026 15:57

Her text was rude, but it does sound as if you've confided in her about difficulties with MIL, which, whilst not directly about money, clearly is connected if you're planning on moving out once you're set up.
You have a very very odd attitude regarding age, OP. Ten years gap is nothing. She doesn't owe you anything because you're slightly older.

Make sure you don’t tell her you are trying to conceive

Random321 · 13/09/2026 16:00

This is unhinged.

You are completely overreacting and as other posters have said it's immature.

Life is too short for to spend time on it.

All you have to say was "yes but we all needthe occasional treat".

The end. Instead you are excalating. Tbh, it sounds like you were spoiling for a fight.

Sorry you need IVF but it's not her fault her either.

ShanghaiDiva · 13/09/2026 15:59

KKD09 · 13/09/2026 15:56

She wouldn’t like it if I did the same thing. When I have made a comment about something, that has nothing to do with her, she wants to get her two pence in, so I think I can defend myself here?

You are both acting like 12 year olds.

Notsosweetcaroline · 13/09/2026 15:59

You’re really hung u0 on the fact you’re a decade older and clearly feel you’ve made it in life more than she has, as you contribute to living with your in-laws. The fact you’re older doesn’t make you her superior.

in reality you’re in a much much worse situation

youre not competing with her op. You’re not better than her, and yes she should not have commented but you’ve clearly told her you don’t like living with your in-laws and are saving to move out. So blowing money on concert tickets when you want to move out seems a little silly.

godmum56 · 13/09/2026 15:59

I am a bit surprised you bother to answer her texts at all...I mean you could actually block her? Do you ever want or need to talk to her unless you are face to face?

H202too · 13/09/2026 15:58

Notsosweetcaroline · 13/09/2026 15:21

Oh dear op. The age think isn’t the trump card you think it is.

I mean she has a point.is that why it hurts so much?

I agree! I was with you op until you mentioned age as a natural respect. I mean come on. Is it 1859? Do males deserve more respect too?

KKD09 · 13/09/2026 15:57

pippistrelle · 13/09/2026 15:48

She can say what she likes and you can think what you like about that, but you don't have to engage with her. It's probably best if you don't.

But it seems a bit rich that you don't want her to talk about you, while you're perfectly prepared to discuss her shortcomings on a public forum.

I mean, all I have done is post the situation for perspective. It isn’t exactly worldwide lol.
