DD14 is a very stroppy teenager and has been so difficult to cope with over the last year and a half. She is bordering on special needs, smokes, drinks, stays out late all the usual teen mayhem. When she gets her own way she is lovely and fun and very nice. She went to her dads for the weekend, we had a fall out over nothing and then when I went to collect her, over an hours drive away, she refused to come home because she wants all the rules changed so she can do what she wants - Stay out till 11 at night etc. After 4 hours of trying I gave up and left her there. No school today as her dad is too ill to drive and his car is not working. Not heard a word from her all day then just got a text saying she has decided to live with Dad. How sould I react. Bearing in mind that her dad is ill but could cope although she would have to help him and if she does she has to change school in her first year of gcse choices? Have held off texting back, any ideas?
