You should really consider doing a coaching session it is well worth the money.
Unfortunately there is very little you can do only work on yourself and stay busy. The only thing I know is that these crisis take time. Your H sounds as if he is deep in some crisis and even though its obvious to everyone else what he is throwing away it takes these WAS many many months to see it.
Stop begging and pleading and start a new hobby. Go take care of yourself so that you always look good. Volunteer or join a new group and make new friends.
Post often. Hang in there. It may take a while but we will be here to listen.
