Hi. My partners daughter who is 24 has been living with us for the past 3 months after returning from a year n Vietnam and previous to that 4 years abroad studying returning only briefly for holidays. Her self entitlement and her expectations of my role within the household has me gob smacked. We have a 9 year old child her little sister who she has made little to no effort with. I wash her laundry, prepare and serve her all meals. She refuses to contribute anything to the household. My partner will not speak to her. Says I must suck it up. HELP. Any advice please.
