Mom didn’t start living until Dad died. She said they were the best 15 years of her life.
Same for my Grandma. She was 79 when Grandpa died, and she lived to be 94. She sold the farm, moved to town, started wearing pants (!!) bought a little go-cart to drive around the neighborhood in... I mean, she cared about him, but he'd been a drinker, and she was very straight-laced. She was appropriately subdued for 2-3 months after he died. But after that, it was pants and the go-cart, and all smiles. LOL! And she said she'd never, ever marry or "go with" a man again. And she didn't. Any of the old fellows in the community who expressed an interest were shot down with withering scorn.
