I'm posting for a friend who is having a bit of an issue. She's been with her partner for 2 years, they have a child together. She has an older daughter from a previous relationship who since day one has spoke to and treated her mum and mums partner like crap. There is a lot of tension between dad and older daughter and not much conversation. Any time he tries to speak to her he gets the worst word out of the daughters mouth. When older daughter is cheeky to mum, mum just ignores it and does not punish her. Mum really isn't sure what to do. She is complaining that her partner doesn't want to spend time with older daughter etc but really can you blame him when she treats him and speaks to him like trash? The older daughter is 9, she screams, slams doors when she doesn't get what she wants, sticks her middle finger up, and swears repeatedly at both parents.
