Your post says your daughter reacted quite nastily. Why did she need to react like that? Is she unhappy about something. Goodness it’s only a name and I think you have every right to be called what you want but don’t take her response to heart. She has a daughter that luckily you have taken into your home plus the child’s father and she reacts nastily when you express a wish! I hope her power of control fades when she needs your support looking after it.
Have you stopped buying papers?
