'But you must also be honest with yourself. A DH who has been dry for 'months' only is not a recovering alcoholic but an actual one.'
Yseulte You're mistaken and in a way that I doubt will be helpful to OP. All alcoholics are alcoholics forever; it then a question of are they an alcoholic in active addiction [which, having relapsed, OP's H now is again
OR they are alcoholics in recovery. Vis the latter, it doesn't matter how much clean time you've got - you are as 'in recovery' on day 1 as you are the bloke next to you who has been abstinent for 20 years.
There is no 'magic time line' - like the 'months' you've suggested - where you 'stop' being an alcoholic. You're ALWAYS going to be an alcoholic and the only variable is are you in active addiction or are you in recovery?
It sounds like OP's DH was in recovery for some months and then - not uncommonly unfortunately
- relapsed.
OP Was your DH in 'active' recovery? IE going to meetings, had a sponsor, working the steps etc? Or has he simply been a dry drunk whiteknuckling it alone? Success in the latter is rare if not impossible; success in the former IS possible but only if he works for it.
It's odd, there seems to be a sudden spike in the number of threads around addiction at the moment but at least you do know that you cannot enable him and something has to change. I hope this does help him risk his rock bottom but I wouldn't count on it OP - and it won't be because he doesn't love you, it will be because he can't have a relationship with you when his primary relationship is the one with alcohol. Painful but true.
And it maybe that he'll just take the time you are away to drink him senseless and barely even noticed you've gone so please ensure this break IS about you having thinking time (as opposed to him having an 'opportunity' to see what his 'rock bottom' would look like.)
