This faces many mums and dads. And it's a tough one except to say that if you are able to say why you and your dad are not together without blame etc, and then explain that he loves you, but he's got this strange idea that by keeping away from you, it will make it ok for you -and him. So validate your boy feeling odd and even confused but make sure he does not jump the conclusion that his dad does not care, that there was something about himself that his dad did not like. Just make sure the child realises he is not the one who has been lacking and try not blame or attack his dad either.
