There is nothing you can do. That is the hardest part for all of us. I still try to come up with ways to save my x. Although, the difference now is I don't act on it. It is really insane ( my x lost his child too) that even after loosing their child they don't see a problem with it. It baffles me loosing their child isn't their rock bottom. I know it hurts. Hang in there and I will be sending lots of love and light your way.
