As far as the book, just leave it. If he wants to talk about it, he will.
I think there are sort of two parts in standing. The first is the part IMP has talked about. You don't' do anything involving your husband that has the goal of getting him back. However, in the background you are doing everything to become a better and happier you. Then, when your husband is with you, or sees you, or hears of you, he see a person he will want to be with! Don't start talks about your relationship, and try not to get tangled up in them if he does. Right now they will be counterproductive.
So, what to do. First, I think, the practical, if you have to do something to protect yourself financially, you just have to do that. I couldn't tell if that was an issue, but be watchful. Then, do what you can to make you better. Try to detach your happiness from his actions. You should look to things that you can control for your own happiness. Even in a good marriage co-dependence is a bad thing. Your business probably confuses things a bit, but try to separate business issues from relationship issues. Get back to doing things you like to do. Even things as small as reading the books you've put off reading. Or renew a hobby. Or, just learn about a hobby you've been interested in, but never got involved with. If you grow, and GAL of your own, you will feel better, and you will be more attractive to him. Of course, if he is MLC, you are in for a long haul anyway, because his wiring is messed up, and there's not a thing you can do about it, really. That is a challenge, but it gives you time to work on yourself, so take advantage of it!
