Family Dinner Fallout Over Brother's Joke

So this happened last weekend, and my family is still talking about it,

so now I’m wondering if I actually messed up. For context, I (27F/M) have always

had a rocky relationship with my older brother “Jake” (30). He’s the type who thinks teasing is

the same thing as bonding, and even when I tell him he’s crossed a line,

he insists I’m “too sensitive.” My mom hosted a small family dinner because my aunt

was visiting from out of town. Everything was fine at first—just normal small talk—until

Jake decided to make a “joke” about me. He brought up something I told him privately

a few weeks ago about struggling at work and worrying about being laid off.
