Went on a date with a girl, got the feeling she was interested by the way she acted on the date and her texts.

Asked her out on another date a week later and she says she's short on money this month and asked if we could reschedule for next month.

I tell her "sure when you want give me a call and we'll go out"

I kinda get the feeling I gave up too fast for a first flake

Did I handle this correctly? Should I next her? Or should I ask her out again?
