I'm heading towards a very similar path, DS now 15 chose to stay with his dad when i moved 3 years ago, there was no pressure, dd came wth me, but his dad, had a new partner and child, DS felt pushed out, when behaviour was bad, dad, seemed to stop parenting and let him get on with things. Six months ago i went and brought DS to me, after dad and gf went away at 2 days notice because he needed a break, DS stayed with his aunty, who hasnt got kids and certainly doesnt no how to deal with a 15 yr old boy. Melting point came and i went and rescued him, discovered self harm, he was dirty , smelly, hadnt eaten properly, didnt sleep ( i know thats what some teenagers do!) in the ast 6 months i have had 2 trips to A+E as DS threatened suicide, ive had every service involved possible, from new school teachers through to police ( when he went off rails and i had to lock his siter in the car for protection) because he was thrashing a garden fork around, because i wouldnt let him go out. Ive paid of drug debts, had money stolen (everything is now under lock and key, and my bag comes to the loo with me)
Three weeks ago he told me he wanted to go back to his dads, and didnt want to finish yr 11 in his new school, i spoke to dad, nothing was done. All of them have been to Greece for dad and GF wedding, when i spoke to DS on phone other day, he told me to F off i was pathetic, because i said if he didnt sort something with his dad he needed to start school and just get on with it...............
Thats it dad says he will sort move back to his, i have had enough, i haven given up on him , but sometimes no matter what you do it will never be enough, i keep having to think i have done as much as i can... SS and care would have been my next option!!
Im so sorry abo
ut the long post just wanted really to say, i can empathise, i hope your DD finds what she is looking for and you find it in yourself to let go (even ifits just for a while!!!)
