I don't understand these women at all. It happens a lot, though, and it makes me sick. Please understand that she did this because of her problems and that it wasn't any statement on how valuable you were/are. All children deserve the best and biology alone should make all mothers very protective of their children. I don't know what goes wrong with women like this. But something goes extremely wrong with THEM.
I'm really sorry that you didn't get the mother that you DESERVED.
