Is your H going back to where you used to live together?
If so, even if you don't do anything (=NC) he will struggle big time just being there, so many things will remind him of happy times together. (not to mention being asked at times "where did you get your nice clothes/bag?) It will kick in more when the pain/ resentment of your R issues eases a bit in a while... you know they say our mind tends to remember the good times more than the bad to protect ourselves.
