Why does good news have to come with bad news? Why not just a riddle? Oh wait ... I think his good news includes some riddles. I hope you find answers to then that you can be comfortable with.
I understand your saying you won't weddin him agin. I work with a lady that had a MLC H, and the D. His new OW lasted the typical couple years and when they parted he spent a couple more working on his state of confusion. After buying a house on the same street he became friends with his original LBS. They now travel and show dogs again, their old original hobby. They rent separate rooms on the road, but share good times. They now enjoy family holidays with their grown kids again, and are best friends again.
She was the first to explain to me that the best revenge is to live the better life. Keep living your better life and if there is any room in it for an old best friend, that may be the right way to lean. Give your gut feelings a little time and don't rush it. If he is serious about getting back to his best life, he will understand that this may take time and he must show he can, instead of saying he can.
