AITAH for telling my sister I won’t pay for her dream wedding after she blew her savings on a pyramid scheme

Alright so this is probably gonna be a long one and yeah I know I might come off like a total jerk here but I seriously need some outside perspective.

My sister Chloe she’s 32 and me 30 we’ve pretty much always been tight. But she’s also always been kinda not great with money. Think like sees something shiny buys it. Takes out loans for trips that kind of deal. Me? I’m the opposite. Been scrimping and saving for ages to try and get a down payment on a house.

So about a year and a half back Chloe gets super into this whole multi level marketing thing you know one of those where they sell wellness drinks. She was convinced it was different that she was gonna make a killing with her boss babe era and all that. I tried to tell her nicely at first then I got a bit more blunt as she started throwing more and more cash at inventory and training. Seriously she must’ve blown through her entire savings we’re talking around $25k on this whole thing. Surprise surprise it didn’t pan out and now she’s pretty much back to square one financially.

Now fast forward to now. Chloe just got engaged to her boyfriend of forever and honestly I’m really happy for her. But here’s the kicker she’s always dreamed of this massive fairytale wedding the kind that costs like fifty grand plus. She knows I’ve got a decent chunk of change saved up and she’s been dropping these hints lately kinda joking but not really about how she hopes I’ll pitch in for her dream wedding since I’m so responsible with my money and don’t have a mortgage yet.

Yesterday she straight up asked. She was like You know if you even threw in like ten grand it would make such a huge difference. You don’t really need all that house money right this second and this is my one shot at the wedding I’ve always pictured.

And I just lost it. I told her Chloe there’s no way I’m paying for your wedding. You literally flushed your savings down the drain on a scam even though everyone and their dog told you not to and now you expect me to bankroll your fantasy? My savings are for my future not to bail you out of your past mistakes.

She got super upset called me selfish and unsupportive the whole nine yards and said I was holding her past against her. Now my mom’s calling saying I was too harsh and that family helps family you know how it goes.

I feel kinda bad that I made her cry and yeah I do love my sister. But I also feel like I’m being put in a position where I have to jeopardize my own financial stability because she wasn’t responsible.
