It must be difficult having done such a good job salvaging your marriage and now not feeling that you can continue the process to reach a "higher" level. What has happen through this is that you have grown and become aware what's important to you. This has created expectations for your H that he does not understand and therefore cannot meet.
I think that feeling that you want more right now is a natural consequence of all the feelings that you must have suppressed and all the pain you suffered getting your marriage back together. Your H does not want to keep reliving it so he avoids the relationship stuff for now. Give this some time you have the rest of your lives together to write that romance novel.
