First time poster here. But it’s hard to read some of the judgemental responses here without sharing a little of my personal experience of this.
I had a difficult separation with a difficult man. My daughter was 12 at the time and she totally sided with him.
On his access says he went to the pub and left her alone. I had to stop this. He was offered daytime but didn’t want it.
My daughter blamed me because she wasn’t seeing her father who subsequently emigrated and lost contact.
He was the easy going, popular charmer while I did the boring stuff like looking after her.
As she got older she became angry, insulting, and abusive which escalated to being violent and destructive at 14.
I tried counselling and various therapy but she abused the therapists.
I am not sure if anyone can understand how terrifying an out of control teenager can be. The OP needs solid support not criticism.
My advice to OP is to seek as much support as you can, see a counsellor, talk to parent line or similar.
You are probably in bits and maybe more so now after some of the scathing remarks (be kind?)
I’m afraid your daughter may have entrenched herself. But she is an adult and abusive behaviour is not acceptable and you do NOT deserve that.
Try to do nothing right now.
Put your oxygen mask on now and learn to float.
I wish you the best of luck.
