Safira: you can't just "put" people into things.
No, a husband cannot just "put" his wife into a rehab center because he is tired of her drinking.
Dee brought up this point: it is either court ordered as an alternative to incarceration or it is self-voluntary. Quite frequently it is in conjunction with a work or job related situation. Many employers pay for rehab.
It all goes back to the alcoholic wanting to change him or herself, not a case of other people forcing that change. SO, SO so many have come out of rehab with absolutely no intent to change whatsoever.
Recovery starts with the suffering alcoholic wanting to make that change for him or herself. Making that change for others usually doesn't work..
