dirty little secret he doesn't want you to know
The secret that no A wants us to know is that THEY are MORE dependent on us than we are on them. They are emotional vacuums and very, very needy people.
Because they are so needy, they usually don't willingly leave our lives unless we force them out. They may leave temporarily, but always return to suck more life out of us.
They are also self-serving. They will only do something if there is something in it for them. If he is to be permanently sober, there has to be reason for him to want to do it. AND, making YOUR life easier & happier isn't a reason.
The pain of drinking has to become greater than the pain of not drinking. That is the ONLY time it will stop.
