Sad truth because children are used as weapons against their fathers. The kids are conditioned to believe their father is dead to them when it was not their choice or what they want. Children nowadays have no choice. They have to live with forceful choices against their will at the mercy of someone else's negative desires. Sad truth about life.
Stop using the children as pawns in your sick game of control! Your hurting and emotionally abusing your child, by alienating your child from family. This is a form of mental disease known as PAS ( I wish he would stop)
It is much easier to build a strong child than to fix a broken adult. The effects of Parental Alienation are harmful and long lasting. Love your child more than you hate your Ex. I tried to enforce this with my Ex but he was stronger than me :(
