I don't believe his family are hurting more than they are helping. Family is about the only people that can crack through a "fog". Family keeps you grounded. Just spending time with family brings back what you want in life, how you were brought up, what you believe, etc.
What you said in the last post really sounds like he is rethinking his decision to divorce. I think, if it were me (not that you asked), I would let him know that you will work toward the marriage as long as he is, and that means getting OW out. You know how it can be to end an affair. He may have been promising the OW things up to this point. He may even feel guilty about leaving HER, if you can believe it. And, the trust issues he has with you.... All of those things make it so hard.
