If your SO died, how deep would be the personal crisis?

Just happened to me. My wife of many years passed away. Yes, it is difficult. I miss her and all that we shared. I would not call it a personal crisis. It is part of life. She was getting older and in poor health, and this was best for her--she had a severe stroke and could no longer speak or move. We had a good life together, a wonderful family and more. But now it is time to move forward. I have even started to date. She is not coming back and I am still alive and quite vital. I would also add that while we did have a shared identity as a couple, I do now have my own identity.
