DSD is 21 and in university. Her mother and DH jointly pay all her fees, housing costs, etc. but they require her to make a monthly budget with how much she's spending and saving.
She called yesterday in a panic claiming she urgently needs her monthly allowance early. When DH asked her what happened to her Christmas money and other savings, she accused him of not supporting her and hung up. DH was feeling quite bad until DSD's mother texted him to say DSD had pulled the same stunt on her that day. On her Instagram we can see DSD has been skiing and to music festivals. She also unfortunately has friends who are drug users (police have been involved) so DH is worrying a lot about where this money is going. DSD has said in the past that her friends think her parents are wealthy and they often tell her to ask them for money on their behalf.
How do you suggest that DH approach this? He wants to tell her that there are no top ups to the allowance and that she needs to learn how to budget and be responsible. She can't spend money and then expect mum and dad to bail her out. But she is acting quite volatile and manipulative so he doesn't know how to handle it.
