Hi Andrea - it may be a little too early for you to write him about all the R stuff - it takes months for their brains to clear up! Be glad though that all his actions are good. And I love it that he got jealous about the cell phone call!
My H and I had a great honeymoon period when he first came back, then very slowly things started to deteriorate a little bit - I actually thought I was the one having doubts about the R - but realize now that I was just REACTING to the subtle signs of my H's depression returning - now that he is back on antidepressants we are both doing much better!
So keep focusing on yourself, but also consider whether you think your H may be suffering from depression?
