My Friend's Sad Wedding Anniversary - Please Help Me? - thank you for a nice wedding message

Today is the anniversary! It is very sad and lonely. His wife left him for another man. I do not know what they say to him via e-mail. Lives in New South Wales and I live in Melbourne ... Please help me say what a message for him as cheerful and pleasant - a little long. Instead of saying, "Move On !"... Thank you:)
