Children will, at various times, blame both parents for a family’s breakup, no matter who is to blame. Don’t try to get your children to be on your side even if your wife was wrong on every count and you, in your perfection, sprouted angel wings. Two people marry and both contribute to the need for a divorce when it becomes necessary.
I’ve met men (and women) who claim to be innocent victims of divorce but I hardly ever buy it.
Look a little deeper at what you did or did not do in the marriage. Get your focus off your ex-wife and ask yourself what your role was in the deterioration that necessitated dissolution of the marriage. Growth, and healing in your relationships with your children will elude you until you assume full responsibility for your part of the family’s breakup.
Until then, until you are cognizant of your role and take responsibility for it, any strategy you employ to more effectively love your children will serve only to create a further wedge between you and seem to “push” the children further from your urgent love. Until you stop all blame and victim thinking, your toxicity will permeate all your relationships, especially the one you want with your children.
