She is anything but selfish. Literally every member of that family is only there because of her selfless deeds (not hyperbole), and they have to talk her into taking their support as a form of thanks. She will never owe them anything by their insistence.
For reference...
She donated 25000 gp, received as compensation for losing her arm and her husband, in order to resurrect five strangers. Those strangers became her family. She still offers to pay for meals and gifts given to her because she doesn't want to intrude on their generosity. Her arm is still holding her husband, and she doesn't need another one.
