answer:Your first responsibility is to protect your child. It is more important than her feelings. Whatever decisions you have to make to do that are justifiable. However, if you have a custody agreement, than you can get into legal trouble if you do not abide by it. At the same time, you might want to temporarily not allow him to see her because he is not responsible.. Don’t decide now that you are never going to allow them to be together again. I’m so sorry that you have to deal with this awful situation. It must be so hard on you. I remember my mother going through things like this when I was a child, and always admire her for holding things together on her own. You can get through this. It will get easier.
