I’m a recovering addict. Addicts are humans and like any other group of humans, we come in all shapes and sizes. Yes, some are manipulative, secretive and dishonest (looking at you @minou123) but so are lots of people who aren’t addicts. Yes, many of us are/were sneaky about drinking during active addiction, but that’s a symptom of being unwell - desperately needing your “medicine” in situations where it might not be socially acceptable. It’s not the same as being a fundamentally dishonest person. If anything, AA has made me a bit too honest and forthright.
It depends so much where this person is in his recovery journey, how seriously he’s taking it, how long his sobriety is, how involved he is with AA (does he do service?), whether he has a sponsor and is working through the 12 steps or just sort of hanging out there?
I would be open and say you weren’t aware that he’s sober, and then ask him the questions above. If he has a long sobriety (as PP said that 1yr point is often considered crucial) and takes recovery seriously, why not? You’d be surprised at how many aedicts are lovely, interesting and successful people you’d never “think” go to AA. it’s definitely doesn’t make you a loser as some people here like to suggest.
With regards to empathy: yes, some recovering addicts can be quite selfish and lack empathy. For some people the way to get over addiction is to focus on yourself (because if you didn’t, you’d be dead) and the byproduct can be that they’re self-centered. But again, that’s not everybody - some people deal with it in the opposite way, by dedicating themselves to service and becoming more empathetic.
Only you can figure out the subtleties of where this person lies, but don’t believe the MN doomsayers!
