So sorry to hear about your H. Jeff's advice is good- don't talk about the R or do/say anything that suggests you want to maintain the R (I know this is the hardest thing in the world to do). If he has space he will start questioning his decisions.
In the meantime start to focus on you and your life. Have you read DR? Start doing some GALing and be mysterious about it (with H).
Also, you might want to read Brandnewday's posts- her H (I believe) left and moved 3000 miles away before they had a successful reconciliation.
