I always think - back in my drinking days, how would I react being approached more than once by a co-worker when in that state?
I wouldn't have listened and I would have been nasty and I would been very proud and resentful...be careful Saphie.
Like others have said, you've already planted a seed by mentioning you're in recovery.
I don't see you can do more than that right now.
You have your journey and he has his.
Maybe one day he'll come to you, maybe not, Saph.
