Good friend wants to meet and make amends - how can I best support?

Hi,

I have a good friend who has recently stopped drinking and has come out admitting he's in a recovery program. He reached out to me a week or so ago and said part of his program is to apologize/make amends for harms caused, and he wants to meet with me to make amends. We're meeting up later tonight.

Obviously, I'm all for supporting him. I'm thrilled he's getting help and making progress to get to this point, and it takes a lot of courage to be able to reach out.

The thing is, I'm having a hard time figuring out how I should approach this conversation. ESPECIALLY because... honestly? I don't think there's much to make amends for, between him and I. He was a heavy drinker for sure but I never felt slighted or harmed or put out by anything. Obviously if he feels like he has behaved or acted unacceptably then those feelings are valid and all parties deserve closure, but at the same time I'd hate for him to be beating himself up over a perceived transgression that either hasn't actually done any harm or may not even be true.

I'm curious if anyone has any similar stories, whether from the recovery side or the friend/support side. I have no idea what he's going to tell me tonight, but I'm not expecting any major revelations or earth-shattering confessions. What mindset should I enter the conversation in, and how can I support him through this step of his recovery?
