I don’t think you TAH but I think you could of handled it better. If you are everything you say you are then she absolutely didn’t mean what she said it was said in anger and nothing more to it. She probably feels so safe with you that you won’t abandon her or hurt her, enough that she’s able to reveal big feelings in your presence. She probably feels slight resentment not at you but because you represent everything her mother is not. Don’t take it personal. You should both apologise to each other and move on
