I have talked to him, and he has been opening up to me a little. I asked for a 6 month to 1 year separation instead of a divorce, and last night he said he would be willing to do that but that I was really horrible to him and I needed to make sure I even wanted the marriage myself because I have told him that he wasn't good enough. I apologized for this, and he seemed open to listening to me do that. I am not emailing him at all. He does want to talk about all kinds of stuff when I see him in the mornings (he comes home late and leaves early), but he generally avoids me. We don't have kids, so there is no excuse to talk.
I ordered the book and am reading it this weekend, but I'm not sure how to detach really. I don't want him to go ahead and get a divorce or stop talking to me completely. We speak so little anyway.
