I was taught that recovery is about sharing our experience, strength and hope. And as already mentioned, allowing the other person to talk. Gawd knows we need to purge a lot of garbage to someone who isn't sitting in judgement of us.
Years ago I remember how at an AA retreat this gal came from out of state in hopes of finding someone she could purge her past with. Sad, but true, often times we cannot do this necessary step in our own communties because people do/will gossip.
So while you may be experiencing some hesitation yourself, perhaps this man has unnamed fears too. Trust is a two-way street. Be that good listener and try not to project into the situation undue negativity, as in the "what if" syndrome.
I, too, was quite cautious when it came time to share those deep dark secrets of my past. But when I found someone I thought could be trusted and began talking, time seemed to literally stand still. I'll be eternally grateful for that woman who listened to me as I purged the old demons. And those words will never pass my lips again...until it's time to share with someone else who is suffering as I suffered.
People come into our lives for reasons that may not always be clear from the on-set. And you don't have to "like" the person, but understand they are reaching out for help. And remain true to your own boundaries...and you'll instintively know.
just my thoughts.
