They may not act like it but you will NEVER erase their love for their other parent. No matter how much you manipulate them or lie to them or deceive yourself, you will not win. They may be angrier than a ticked off bee for years, decades, even but deep down, that child of yours LOVES their other parent! Even if you cut them off from the target parent and move across the world/country, whatever. Even if your children never see their other parent again, they will still love them!You will never stop them loving their other parent, even when you make them think that parent is evil.
