The night in jail after a DUI was my RABF's wakeup call. He's been sober ever since, for almost two years now, through some pretty hard times (job loss, foreclosure, near-constant anxiety over his financial problems).
He didn't do AA, but he has an excellent therapist who understands substance abuse issues, whom he sees weekly. His commitment to learning more about himself, accepting responsibility for his actions, and most important, not drinking, is the only reason we're still together.
