i have known couples drift apart when the drunk sobers up, i have heard people say they would rather have the drunk back than the sober one
but i have seen what happens to people when they suddenly decide they no longer love there partner and break up the home
after a short while the partner finds out that he misses what he was used to and if the other partner will not take him back then he is out in the cold and wishing he never left in the first place
some have gone back on the drink again rather than face life of being on there own as its a huge change
so the best thing to do is to wait and give time time dont make any major changes in your home life for a good year or two
give each other time to adjust to the new sober person
