LS, I also think it is time for you to start thinking of being without her in your life and finding things that make you and your Son happy without her! I am trying to be gentle in saying this to you. I'm glad you are posting, talking to your Pastor, talking with you family, prayer (for a way to get through this agony for you and your Son). You WILL get through this when you start thinking more of what you can do for yourself through this difficult time! Do you have close friends to go out with? Staying in your house and thinking and worrying won't really help. Pick out the most positive people in your life and invite them for a coffee somewhere in a totally new place making new memories that are just for you. Visiting places that you used to go with your wife won't help. Try giving yourself a break and be gentle to yourself. Your Son needs you more than ever now! Take care, LS, and we're here for you!
