I know what you mean. The same thing happened to me when I was first widowed. Its hard enough to get through the days without him, but the phone calls & mail addressed to him made it really rough.
Now, 5 years later, I live in a new state & get mail addressed to my late husband! Yesterday, he received an offer for supplemental life insurance for funeral expenses...a wee bit late. How did mail addressed to him find its way to a house he never lived in (1200 miles from his last house)??!!
