What I was trying to convey is that he's confused and that his anger and niceness are closely related. The opposite of love is indifference, not anger/hate. A lot of us on both sides of the fence are confused on the outside because we are confused on the inside.
I don't think you should go out of your way to let him know anything. If you asks you a question directly, answer him directly, but tactfully. You don't need to offer him any information. I have mostly kept my personal life out of my conversations with XW and certainly out of her view. I offer nothing about me because SHE wanted out. So she IS.
Work on YOU. As Radio Shack says, "Don't just buy stuff. Do stuff." Explore previously enjoyed pastimes, re-new old friendships, try out new hobbies, read about what interests you...simply make yourself more interesting and others will notice. He will notice. You will like YOU more. You're a great investment. Invest in you for the long term. SHOW him he's missing out on the new and improved you. HiS loss. His choice. Oh, well.

p.s. Hold your head high. Rise above this. The world is full of wonders, of which you are one.
