I've had nearly the same thing happen to me off hinge. Though we were only talking for a few days she hit me up for gas money to get home from work because her mom's new card hadn't come in yet or something like that. It was like 30 minutes after I got up for work, she asked for 20 but it didn't quite feel right so I sent 10 feeling bad for her. She promised she'd take me out to lunch the next day but she ghosted. Shit happens but we live and learn.
