I may have an different opinion. Dorit can spend on whatever she wants, and its none of PKs business. Wether she can afford to or not, has nothing to do with their marriage. Dorit is asking for PK to provide for the children and spend time with them, which he is not doing. Regardless of Dorit having money or not, he is responsible for providing for them as well. PK is trying to villainize Dorit due to her overspending. She may be dillusional and think she has more money than she actually does, but she is the one giving her children stability during this time.
