Interesting post in light of your literary leanings Nick.
Hemingway of course never got over Hadley, his first wife, though he instigated their separation and divorce.
Fitzgerald never got over Zelda either, but not in a good way...pretty easy to argue that she hastened him toward his death.
I met my first wife on our first day of work. We began dating and were married before the first year was up. We had three children and were extremely happy, and almost never fought. She was my true soul mate. I lost her to the beast of breast cancer over ten years ago. Not long after I left MA for FL, I met a widow on line. We got married not long afterward. My new wife of ten years is an angel of mercy to me and I loved both of them dearly.
