I am so sorry for your loss. It is heartbreaking; we all know that from first hand experience. Unfortunately, the only way through is straight through the pain. There is no way around it. Feel everything. Cry, miss your boy, remember him and love him still. I lost my girl 1 year ago. I miss her and think of her everyday. I chose to get another dog which helped me deal with the loss, but everyone is different. My puppy, now 11 months, gives me a purpose and makes me get out and moving each morning. Just like my Daisy before, everyone stops to talk to me when I am with her, which is good because I tend to lead a more isolated life. Dealing with grief in isolation is not good. This forum helped a lot in that I found like minded people who helped me through the loss and also the emotionally complicated adoption process on my thread "Adoption after loss." The best thing to keep in mind is that there is no time limit or right or wrong way to grieve. Everyone is different, but you will find much support here.
I wish you and your wife peace through the process.
Lori, Daisy's Mom and now Luna's Mom
