If she needs to buy him a ticket something tells me he doesn't have a job or not a very good one so he probably woildn't be paying much child support.

Good point! It would take years to have many children, so the OP would have plenty of time to pressure the loser husband into making something of himself. Revenge is a dish best served cold.

Better just play some poker to get the money. You'll have fun and no work with an ex-husband and children you don't want or need.

How is this a catfish? As far as we know he has not lied about his identity, nor did he profit from the situation since presumably she bought the ticket for him as opposed to handed him the 900 dollars to buy the ticket given that she specified he missed the flight as opposed to "didn't buy the ticket and ran away with the money"

Some catfishers operate that way — getting their victims to piss away money is just one of their sick pleasures.

Maybe he didn't even miss the flight but bought himself a free ride to a nice holiday.

Hey, sometimes you get in a LDR with someone who can't always afford their own flights. Had to do that with my SO since money was a bit to tight for him to visit on his own.
