Not sure what to do. DW is really nasty to 11yr old DD. DD does misbehave. DW thinks DD is exceptionally bad and has "betrayed her trust too many times". DW admitted she would be happier if DD left. She claims she loves DD but evidences this by saying she buys her nice clothes etc. DD said she wants to go far away from her mum. But she doesnt want to leave her younger sister who gets on fine with DW. DD is imo a fairly normal girl with a strong tendency towards play and fun and games and a hatred of hard work. DW is very strict about work and hates mindless and messy play. I get on ok with DW but find it very difficult living with the shouting and crying. DW things she has done nothing wrong and anyone would act the same as her. She would never accept parenting advice or therapy.
