I found your post quite by chance, and I couldn't believe nobody answered. I know it's hard to lose people, so I'm writing.

Some guy in the 30's wrote that "there is no doubt the universe is unfolding as it should." I think that's true, things are just meant to happen. Your time with your wife came to an end, now comes your time with other people. Try to enjoy it, she would want you to. You have the good memories to carry with you.

Hope it helps. Good luck to you.
