I was thinking as I read the thread title that somewhere in that sorry tale will be a father who doesn't take any of the responsibility for having brought two children in to the world.
Again, do you know them and more that's be released?
Because at the moment, you have a shockingly abusive and neglectful mother, who denied the father PR to the second child. Moved away and did what she could to stop him seeing the kids. Now usually, you may say she must have good reason. But given she is so evil, she could I'll her own children. Its not beyond the realms of possibility, that she was the problem. Not s man who could be arsed.
He was araed enough to call SS. And not to stick the boot in. He was right to be concerned.
