My DDs mum and my partner left a year ago, older DD who's 12 has generally coped well considering the situations, she's had ups and downs. Whereas 8 year old DD has had a really tough time, she was very close to their mum. She's rarely happy which is horrible to see, she's usually upset or angry. She doesn't listen to me at all, she shouts, hits and kicks when she's angry. She's getting into trouble at school because of her behaviour. She talks about her mum a lot, missing her, wanting her to come back. It's hard to know what to say, she's too young to fully understand why her mum left and so she either blames herself or me. I end up feeling bad when I discipline her because she shouts things like "you don't love me, you hate me, no one loves me". I know she's just shouting things for the sake of it but I worry about her actually believing that.
