Sophiasnana, if you really want time together get yourselves along to a dance school. You can't be more together than embraced in each other's arms as you dance round to, slow, slow, quick, quick, slow.
30 years or more of marriage makes you both comfortable in knowing that you don't have to do everything together. You wouldn't read a book together and for my wife and I, and many others too, we have separate bedrooms. So don't go getting anxious because others watch TV together.
As for the future, it's only natural to have some concern. When you made the vow until death you do part, death was never on the horizon. I worry two fold over that. Being bereaved over the loss of my darling wife, or, going first and leaving her alone to cope. My wish would be to emulate Prime Minister James Callaghan who died just 11 days after Audry, his beloved wife of 67 years.
