I live in PA and have 2 sons in OH who live with my ex - in her house, she feeds them, etc. I am continuing to pay for the older one who is now just over 19 yrs old.

I also give them cash on the side and they both have credit cards which they frequently abuse by hitting taco bells, gas stations, etc. (Nothing crazy).

The ex gets her support from OH for my youngest - but I'm wondering how I should approach cutting her off for the older one? We're not on terrible terms but I'm sure she's going to balk and say she pays 'everything' for them. This will definitely cause some stress.

Not sure what to do or when to say enough is enough. Maybe just a hard dead-line? Or just pay the kid directly?
