My Dad was 100% devoted to Mom, through many episodes of her depression and medication problems. They were married 61 years and she was 83 when she died suddenly at home, with him right there with her. I met them in the Emergency Room and the first thing he said to me was, "I'm not sad, this solves a big problem for me" which I thought was so cold. The day after the funeral he wanted my sister and I to come to their apartment and get rid of all her things.
We were still processing her sudden death and just beginning to understand mourning and he just wanted all her personal things out of his space. My sister and I met at the apartment and started going through her things, remembering her in this dress and wearing that scarf, etc. He didn't help at all, we had to make all the decisions. Four hours into this he came into the bedroom and said we needed to finish already, he had plans to go out.
We kept very little and all of my Mom's things were donated or thrown away that day.
What I didn't understand back then, but understand today is that she had been a bigger burden on him than we realized and that he was having more trouble handling it than we knew.
Two weeks later he broke his hip, had surgery and rehab but has never been the same. After 3 1/2 years in an assisted living facility, last month we moved him to a hospice facility. He is almost 90, in a wheelchair, almost completely deaf, has some dementia but still knows me when I visit and knows how many minutes until the next meal.
Such a sad ending to a long, loving marriage.
