I read this thread and I think you should go back and read the excellent responses you got, especially on page 2. They all have a common thread which is you can't control H, can't help him come out of the depression, can't make him contact the kids, etc.
All you can do is work on yourself and be a good parent to the kids during this difficult time. In my sitch, my H left the end of February and has never sat down with the kids (his stepkids) to talk abt how they are, why he left, what will happen. All reasonable conversation topics but while our H's are in their fogs and/or depressed, they can't do it.
So, you just have to be patient with H and in the meantime, take care of yourself. Get busy, move ahead with life w/out H and remember that you are both on your own journeys. Hopefully by doing the work you need to, and giving H the time/patience to follow his own journey, you two will end up on the same path again some day.
As far as responses, I found it helpful to journal regularly so the thread doesn't get lost on page 10 of 20, and as I said, you received some excellent feedback previously... go back and read those because they tell you everything you need to know, and all you can/should do right now.
