I just want to say I'm glad that you are findnig some peace and balance during your separation. Who knows what will happen with your H? The separation is pretty fresh, and will be for awhile I think (your H sounds like he is really enjoying is furniture buying spree).
I'm glad your focusing your time and energy on you! And you know, in 5 or 6 years, D12 will be off to college too, so its a bonus that you are developing other parts of yourself right now besides Super Mom.
