The stove, it is hot!
You know the adage about touching the burner. Well that is this. Your DD is going to do this, again and again and again. You know.
That you can't stop or change, you can only change your reaction.
I know how hard it is not to take this on board. Why is she saying that? Am I a bad Mother that she feels she has to bail and find a new one? Why would she say something so hurtful.
As you know, all is not right or ok with her, so this behaviour and lashing out will continue. You can choose not to look or at the very least, get some defenses up there.
It's ok to detach you know.
