Losing a spouse is awful & definitely not a plan intended in original's God plan. Nevertheless each human has its own ability to choose. Yet, weather she chooses to forgive or not, even that does not guarantee her return, but one thing is certain that God has a plan for your life with or without a wife. The pain is horrible, i have gone through myself but Jesus is able to restore you, clean your heart and let the rest be. What profit a man if he gains his marriage but not be aligned with God. You are loved because Jesus lives and He is able to keep you even if the person neve returns and never forgives, what truly matters is your heart and your relationship with Jesus. I pray that the Joy of His salvation returns into your life and he heals your broken hear no matter the outcome.
