Dear Abby: My husband’s 24-year-old daughter shouldn’t still be on our budget, right?

DEAR ABBY: I’m in my early 30s; my husband is 46. We have been married three years. He has a 24-year-old daughter, “Kiki.” Kiki has always been spoiled and catered to; she learned how to lie and manipulate during her childhood.
I have tried to help her because I believed his family when they said she’s trying to get it together. Kiki has a DUI, and she got evicted when her parents asked her to pay her own rent, rather than having them pay. They give her cars, but she wrecks them and then leaves them on the side of the road.
We have a 3-week-old baby and a mortgage. I don’t think his daughter should still be in our budget, but my husband can’t say no to giving her money. Kiki is a habitual liar and user. She can’t pay for gas because she buys weed and alcohol instead, confident that everyone else will pay when her utilities get shut off.
I don’t think it’s fair for us to pay her way. Is 24 young enough to still need this much help? My husband is very defensive about it. — USED IN NORTH CAROLINA
DEAR USED: Considering this troubled young woman’s history, your husband has made a big mistake by fostering her dependence on him. Independence is something she may have to learn in increments. Your husband should sit down with Kiki and explain that he loves her, but she must now find work to support herself, and that he will help — for a set period of time — as she adjusts to shouldering responsibility for herself.
If he is still paying her rent, there should be a firm cutoff point. No more cars, because she’s a danger on the road. She can use public transportation. And if there are any more problems because of her substance abuse, all bets will be off. The time to draw the line is now.
