Bless your heart --- Please don't project. Why destroy today and tomorrow by worrying? Worry doesn't help anything, and it doesn't stop anything from happening.

You're only driving yourself insane!
If he is in good health, rejoice in that and keep him close! Enjoy the time you have! You could have MANY years left together so enjoy those!
My husband died 12 days before our FIRST anniversary! It was a 2nd marriage for both of us obviously, but we didn't know he was sick when we got married. We were told he was terminal after we'd been married for 4 months.

I nursed him until he died.
YES you CAN move on after a loved one dies. It's very difficult for awhile. You must grieve, and that can take quite awhile for some. We all grieve at different time "schedules." But after we've healed to some extent, we do go on. That doesn't mean that we don't MISS our loved one or love him anymore -- it just means that we're able to function now, and get on with our lives.
Please don't rain on today. We aren't even PROMISED tomorrow so rejoice in today!! That's all we have.

God bless you BOTH and take care. Hugs, Lee
