u/According_Party_202

I (25M) have a younger brother (23M) who’s always been a bit reckless with money. Over the past year, he got a decent-paying job but spent most of it on partying, designer clothes, and trips with friends. I tried to warn him a few times to slow down and save, but he always brushed it off, saying he was “living his best life.”
Fast forward to now — he lost his job a couple of months ago and has basically burned through everything he had. He recently asked if he could move into my apartment “for a few months” until he gets back on his feet.
Here’s the issue: I live in a small one-bedroom place that I worked really hard to afford. I value my space a lot, and I also don’t fully trust that “a few months” won’t turn into something much longer. On top of that, I’m worried he won’t actually change his habits and I’ll end up supporting him entirely.
I told him I can’t let him move in, but I offered to help in other ways — like connecting him with job opportunities, helping him fix his CV, and even covering groceries for a bit while he figures things out.
He didn’t take it well. He said I’m selfish and that family should always have each other’s backs. My mom also called me, saying I’m being too harsh and that I should “be there for my brother in his time of need.”
Now things are tense, and I’m starting to question if I made the right call.
So… am I wrong for saying no?
