Perhaps you two made lousy choices as to who you decided to be the
other parent. If so, that is YOUR problem and YOUR fault.
"No matter what you think of the other party - or what your family thinks
of the other party - those children are one half of each of you. Remember that, because every time you tell your child what an idiot his father is, or
what a fool his mother is, or how bad the absent parent is, or what
terrible things that person has done, you are telling the child that half of
HIM/HER is bad.
"That is an unforgivable thing to do to a child. That is not love; it is
possession. If you do that to your children, you will destroy them as
surely as if you had cut them into pieces, because that is what you are
doing to their emotions.
"I sincerely hope you don't do that to your children. Think more about
your children and less of yourselves, and make yours a selfless kind of
love, not foolish or selfish, or THEY will suffer."
