I have name changed for this .
Another voice here adding yo the 'there is nothing you can do to make her give up'
My DHwas a alcohol, to start with when we first met we both put our high alcohol consumption down to our environment as we both worked in pubs but as time went although i still enjoyed a pint or two at the end of the night my DH ( unknown to me ) would have a couple during his shift then more at the end of the day .
Over the years it increased so we both got out of the pub game and went for different jobs .
I use to work all day on Saturdays so he would do the shopping , I discover after a few weeks he would go to the pu spend way to much then not have enough for the shopping .
His drinking increased more over the years to the extent he would drink gin at 7am to 'steady his nerves'
I ended up getting my DB to take our car away as I was very concerned DH would drive to the pub and back.
I tried everything , hiding money , taking his cash card , threatening to , and actually leaving hom .
Occasionally he would give up for a week or two , go through DTs ,violently ill, shakes , disoratation etc . Then say "see I can give up when ever I want " and the hit the drink again.
In short there was nothing I could do , he self distructed.
