"Give them room and credit to figure it out"
So true! My daughter's bio dad is a suspected alcoholic (DD says he is one) and although not diagnosed, I would bet my life's savings that he is a narcissist. For the longest time, I feared she bought his BS and brainwashing against me. (And maybe when she was younger she did) Now she's older, though, she can see right through it.
What a wonderful moment between you and your daughter. As parents, sometimes we wonder if our children see just how much we love them and if they know the mountains we would move for them. It sounds like your daughter does.
