I have known a number of widowers who married again very soon after their wives died. They couldn't stand being alone, couldn't cope with life in general. But the faster they remarried, the sooner they regretted it. It was case of "any port in a storm", "she must be alright", and never stopping to think that the new woman could not possibly replace the lost one. In some of these cases, the subsequent divorces were very expensive. Warning to widowers - watch out for gold-diggers. And think before you leap.
