Walter, like Danny I am shocked by the sudden turn of events that your home coming has revealed. Here is the reality of war, and not movie-land's happy ending of reunion with one's loved ones after much travail and suffering. I suspect that this very sad experience was far from unique amongst returning POWs. With very restricted news from home anyway, and NoK not wishing to add further to the everyday trials of those behind the barbed wire, the truth was only fully revealed following their return.
Even those who had survived the home front could have been changed by the war in the meantime, ditto those returning from camps or overseas campaigns. For many families the war went on for decades after August '45, for some it still does....
My sincere condolences, Walter.
