Friend's Lies Led to His Stranding

AITA for leaving my friend stranded after finding out he’s been lying about being rich?

So I (19M) have a friend, Jake (20M), who never shuts up about money.

Designer shoes, “business deals,” always calling people broke as a joke. Last week at a party,

someone asked if I wanted to split an Uber. Jake immediately says,

“Don’t worry about him, he’s broke anyway.” Everyone laughs. I don’t.

Two days later, Jake texts me saying his car is out of gas on the highway and asks me to send

him $40. I reply, “Thought I was broke.” He gets mad, but here’s where

it gets wild. One of our mutual friends DM’s me screenshots from Jake’s private Instagram
