If there is any love left, fix the marriage. Get professional help and patch it up. I lost my wife 8 years ago this week and wish every day that there had been something I could have done to keep her. She took her life and there has been no one come close to a relationship that we had. You both still have a chance...go for it.
Prayers to you for the loss of your wife. Don’t look for the relationship you had, look for the one God is going to send your way.
Sorry for your loss, vetvetdoug.
