I too am separated in different countries and I took the NC route... mainly as a way to set my boundary as H sent angry emails with insults (which I don't think your H would do), then I got weary to do anything. I also wanted H's pain to ease off a bit for him to perhaps miss me. I felt that otherwise there is no chance for us to work together.
So far... I don't know if it was good or not. It has helped me loads to detach, it's as if he was another life so many years ago... but my DB coach told me we're way too disconnected now, even people who have been deployed contact more often!
Recently started contacting again as we have some things to sort out, and it has been amicable so far.
In the early stages of my stitch, the coach used to tell me to avoid any R talk and keep the emails to positive chit-chat.
Btw, we've been separated for 6mths and NC went on for 3mths, I even ignored H's birthday.
