I love my 18 year old dd. For years it was just her and me. Her dad was violent and after our divorce she chose not to see him as he was pretty vile to her too. We have been through normal ups and downs. I now have a wonderful partner and we have lived together for the last year and my dd resents him. He tries so hard and is brilliant with her but she acts really spoilt and is horrible to him. She has a bf now and is talking about moving in with him. I have tried everything but she has become lazy. Bunks off college. Doesn't want to work. Refuses to contribute financially when she leaves college in a month's time. Is messy and rude. I am at the end of my tether and can't help but be relieved that she wants to move out. What have I done wrong? We used to be so close. It could be because of my partner. That's what she wants me to think. But honestly it started before then and I think it's a long excuse for her to behave badly. Does anyone else have teenagers they don't recognise from the delightful children they used to be??
