Tell your husband to back off from this poor girl. I literally see her begging, with heart bledding, desperately struggling under his authoritarian control. Why does your husband stil act like a piece of cold stone? Why does he prioritize the need to be right over the recognition of her suffering?
Back off! If you need to divorce him, do it! For the sake of your daughter's life, a young life, which hasn't opened her petals yet. She has so much potential that can be unlocked when free.
I was crying while I was reading it, as a mere stranger, but also as a mother of two daughters, and also a daughter of my father. I was in those shoes before, I knew her pain like it was cutting into my skin.
You can't persuade your husband, he is deadly blocked like a deaf person. Save your time. Your daughter is so gentle, so patient, and so wise. She will definitely be successful in her way. Leave her alone, let her try, she will be okay. Already her maturity and ability to express herself is beond her years. Let her decide her own path away from your husband and she will do much better than being enslaved under your husband's whip. He is drunk on control and blind. Just as you would not allow a drunk, angry person to drive your car, do not let your husband drive your family off the cliff.
I can't even explain it any better than what your daughter has done. The problem is not on your daughter's side, it's on your husband. He treats a human like a machine, poor thing, he doesn't understand a bit of emotion. To him, he just wants to be always superior. He toys your daughter like his own puppet, he decides your daughter's breath, sight, mind, existence. The most outrageous part is that he even puts such an enormous burden on your daughter, by claiming she needs to be responsible to everyone else, as she owes the whole world. This is not the tough love he believes he is giving. He is delusional. This is someone who, with his own image of unattainable success, is ready to tread upon his own daughter to squash imaginary failure out of her. At the same time he is obstinate like a child, unwilling to recognize his own faults. I don't know how, under such a father, a male dominant figure, how can a girl ever grow up as an independant and confident woman, with sufficient self-esteem to be happy with the rest of her adult life? This is abuse. Your husband is abusing your daughter, beating her physically, and worse, emotionally.
Your daughter is a blossom that can bloom into her own successful, independent, dazzling flower. Don't let your husband crush the bud befofe it opens because her petals are not the colors he wants.
Back off before it's too late!
