Sorry you are having such a rough time today. I hope your visit to your friends house cheers you up. Get a good nights sleep tonight, tomorrow is another day and it will get better for you.
I would not suggest anymore books to help your H. It is up to him to discover what will make him happy. You leaving did not make him miserable he is doing all that by himself. Don't let him control how you feel or make you feel guilty.
It is like telling and alcoholic he is one. Until he discovers how to make himself happy nobody not even you moving back in with him will ever do that. Take it from someone who woke up and figure out he was the problem and not his W. Keep doing your own thing its the best you can do at this point.
Cheers and tread lightly at your H house this weekend.
