Mila, My H didn't sleep either and now I believes he sleeps even less. He appears very old and very tired. One explanation I was either told or read about is that depression disturbs hormone levels including serotonin.
Another reason your H may not be sleeping is what he doesn't deal with during the day, the night brings the monsters out to play and the sitch will not be denied. If they do sleep, their dreams haunt them.
They will do anything to try and outrun the pain. The thing they need to do is stop and deal with the issues that are causing it. Unfortunately, they have to figure that out on their own...
FTR, I don''t believe your H is 'done' with you either. Your connection runs deep. It is buried for him right now, but it's still there. If he ever deals with his issues, and starts to peel back the layers, that connection will be revealed to him as well. It's what keeps him returning. When he is strong enough to embrace it instead of trying to outrun it, that's when he'll come back for good. That is, if you'll let him...
You are doing so well! Stay the path, it will work out exactly as it is supposed to.
