Hey Seattle,
Yes, I was going to say that email has been very, very good for H and me. I don't know that it will save our M, but it definitely has given us opportunity to say more vulnerable things, share more of our feelings, apologize to each other, chat about books and current events, etc. Of course, we are both writers, so I don't know if that might have something to do with it. It's rather ironic, in a way, because a lot of our early courtship was based on emails, too. I guess the upshot of my advice is: try it, and see if it's good for your R.
