I know you want to be helpful, but I think it would be best to suggest that he google affairs and let him select a site that would be helpful to him. There are a number of excellent sites out there and he will locate them w/o any problem. Do not share what this site w/him or the books that are directly related to this site. You want to keep your postings as private as can be and do not want your info to be used against you at a later time.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
