Eyes, Here is my professional opinion on your situation...ha ha, just teasin ya.
Seriously I wanted to say that things sound as if they are progressing really well and to not get discouraged by irritable behavior in your husband. This is a relatively new development in your relationship and it will take a while for him to adjust to the "new" you.
Right now, I would venture to guess that he does NOT trust that these changes are real and lasting. And who can blame him, right? On the other hand, requiring someone to continue to 'prove' themselves is downright cruel. I hope that the two of you can continue to build the trust level back up and the intimacy will follow.
One month is a very very short time for a major change to take place. Try to not read too much into his moods and allow him time to work through everything that is going on. There are SO many questions that are running through his brain right now and time and consistency is what will answer them.
