My H actually never left home but he had an 18 month A with one of his staff and when I found out it was touch and go for a week whether or not he would go.
Once he recommitted though at the end of the week things seemed to fall back into place fairly quickly, like with you, BUT I knew that he still wanted to let the OW down gently and I had times of feeling distant and worrying. He was 100% transparent and was caring and helpful like your BF is being.
Just to let you know though, it took a full year before he out of the blue apologised for what he had done and said he couldn't believe he had acted the way he had. He said that he never thought he would be the kind of guy to act that way and he was embarrassed at being such a cliche. I don't know what prompted him saying those things but it really helped in the healing process.
So be patient, things will happen when they are meant to.
