I understand the promises part...it is best to make no promise then one your not sure can be kept...
My H has had one slip...of course he deeply regreted it...and got right back up and has been doing good since Jan 10th...when he did slip I kept my cool...but because I found him passed out cold after he called me for help I did call 9-1-1 and have him taken to a hospital instead of taking him home...like he sort of asked of me to do....
Your right to acknowledge her pain in all of this...and I am really proud of your efforts at DB'ing...in not snooping...I know how terribly hard this is...but you know what it shows about you???...it shows that you have a strong will of determination...you can resist snooping even though it would be easy for you to do to...you are resisting alcohol even though it is around for the buying...this is your greatest strength...build on that...she will see you as a stronger man and this will reassure her that the weak man is "leaving the building"...you are bettering yourself...keep it up...I know it isn't easy...I have watched my H along his journey of rehab...so I applaud you...
