I’m currently sitting at home feeling like the worst person alive because I’m stressed about money when I should be grieving.
A woman who was basically a second mother to me passed away. I grew up with her kids, and even though we had a bit of a falling out a few years ago, she was always so good to me. I live 5 hours away now and couldn't make it to the funeral today, so I ordered a big flower arrangement for the family.
It cost me $90.
The thing is... I am broke. Like, actually struggling right now. My mom chipped in $20 but I’m still out $70 and it’s hitting my bank account hard. I’ve already paid for them so there’s no going back, but I’m sitting here with such bad buyers remorse and then immediately feeling like a monster for even thinking about the price tag.
Like, this woman’s kids (who are basically babies, only 18 and early 20s) and her husband just lost the love of their lives, and here I am worried about $90? It feels so selfish. I know the flowers are the right thing to do and I know they'll appreciate them, but I can't stop the financial panic from creeping in and it's making me feel so fake.

I’m struggling to even be around my best friend right now and I need to vent.
I’ve been friends with "Sarah" for 15 years. I’ve known her husband for their entire relationship, and he’s a genuinely good guy who adores her.
A while back, Sarah started seeing a coworker. To be honest, I think the whole thing with the coworker is gross, but it is really the way that she handled it that got to me. She wasn't conflicted or guilty at all; she was actually giddy. She’d send me photos of him, talk about how "hot" he was, and went on and on about how amazing it felt to be "wanted" like that. She wasn't looking to leave her husband for this guy; she was perfectly happy to just continue the affair behind everyone's back indefinitely. She wanted both lives.
The only reason it stopped is because the coworker was the one to pull the plug.
Since he ended it, she has done a total 180. Now, she’s acting like the world's most devoted wife. She constantly sends me "cute" photos of her and her husband hanging out, or them at dinner, acting like they’re the happiest couple on earth.
Watching her play this part while knowing she’d still be cheating right now if she had the choice is making me feel physically ill. I feel like by staying silent, I’m helping her gaslight her husband. Every time I see him, I feel like a liar.
I don't want to throw away a 15-year friendship, but her lack of remorse and the way she’s just "pivoted" back to her marriage is terrifying. How am I supposed to keep responding to these "happy couple" photos knowing she was happy to lie to him forever?
