My wife and I did the same thing. There were times when she wasn't working to either to raise our kids (I helped!) or when she was ill. We were a good team and when we finally became empty nesters, she got cancer and died back in June 2017. Cancer sucks! I've since retired and moved out West to Colorado Springs to start a new life. I'm ready now for a relationship with a good woman, but NOT ready to play the dating game. It's been 38 years since I've been a single guy in the dating scene and a lot has changed since then. I'd rather meet someone crossing paths during day to day life. That usually works out well! Wish me luck!
Some years ago a family friend lost her husband and I told her to go and love some more. She was angry that I would say that. She was still grieving and not ready to envision life ahead. I hope you can find someone in your life to share what lies ahead. I'm sure your first wife would too.
