Miracles DO HAPPEN--I've seen many, many of them. My first husband is one. He is a shining example of recovery in action--now in his 34th year of sobriety. He is not a perfect man, and I have no wish to be married to him, but he is a good man, a good dad to our kids, a good husband to his second wife, a good friend and sponsor to the guys he works with, and was a valued employee until his retirement a couple of years ago.
You don't have to force or rush the trust. It comes with time and recovery (on both sides).
