that's not okay. people should be able to change their names and have other people, their loved ones most of all, respect that decision. when i transitioned, my family had no issue using my new name even though i'd used my old one for 22 years. there were mistakes made at first, but it's a matter of love and respect that the people close to you try to get it right. if she truly can't wrap her head around a new name for a person she had only known for a year and a half, that shows a huge lack of respect. i wouldn't associate with anyone who insisted on calling me something i didn't want to be called.
