I know it may seem sad to hear of your H being in such a state with himself. You can't help him though, he has to find his own way.
The drinking sounds normal. The lonely is about right (remember, you can't solve that one) My W hasn't been sleeping either, it's thier mental state. This is a typical view point. Feels inadequate, you deserve better, without him you could be. It's all about self esteem. They feel unloveable, they are in their current state even though WE love them, they don't love themsleves. Looking back like that I would see as a chink in the armour, he is beginning to realise what you had even if it's only negative things at the moment. Speaking positively of you, well that's good. My W does nothing but praise me to MIL. I heard that from her today. Seems a little weird, but after all, they know at their core how good we really are.
Once you feel strong enough, some contact (email) would be nice. Did you tell H that you still stood by your M when you told him you had let go?. I told my W that I still believed in us and our M despite what she had said and done and that whilst I respected her decision to be apart, I didn't agree that it was over. She should respect my choice as well.
MY W is proud and stubborn, they will work it our eventually. Whether we are here to see the results remains largely in our hands. We are the ones in control you know, not them.
