When I was 29 I fell in love with a wonderful, older man. Despite the age difference it was a romantic dream for both of us. I guess we thought we were Annette Benning and Warren Beatty types. He had no health problems whatsoever when we married six years later. Within seven months, though, he was diagnosed with cancer metastasized to his entire body. He died less than three months later.
It was a grueling experience, and there were moments when I thought that I, myself, would not survive the emotional impacts. Luckily he had good health insurance. His prognosis was so bad, that this 57 year old man was referred to hospice the same day his cancer was diagnosed. He had no adult children, and I was his primary caregiver (with hospice support) at home until almost the very end. I was glad to be there for him, but to say that it took a lot out of me, is an understatement.
My point mainly is, when you marry anyone, you take on not only civil commitments, but emotional as well. "'Til death do us part", and caring for a dying individual is similar to caring for an infant. Only, much sadder, with the loved one's suffering, and your own imminent loss. (If you didn't love the spouse and married for money or benefits, it would be a nightmare. And, good luck trying to fob off the work on someone else.)
Yes, I am now 58, and I anticipate getting survivor's SS in about a year and a half. A bit earlier, and a bit more money, than my own earnings record would garner. Coming at a high price, though.
