Now for my real answer...
I trust my wife now... sort of. It's taken almost two years, I'm still very cautious, but I can honestly say I no longer live in fear which I count as a kind of trust. What I won't allow is for my trust to be blind, but as the days go by and she remains sober I find my fear and distrust slowly ebbing.
That said, it would take only one drink for her to destroy all of the trust she's rebuilt within me, and I imagine the setback would be further than before.
