There is NO one answer to this.
I had a friend who had a 16-year-old son who was dealing drugs, about 20 years ago. The son was hounded by his drug-sources and was possibly going to be hurt badly.
So, the parents moved him elsewhere-----paid for an efficiency apartment and utilities. Put food in the frig every week. Paid not one cent otherwise.
They knew for sure that the child would no longer be endangered if he stopped dealing drugs. He would continue to do minor small jobs for money, to take drugs, but he would not deal drugs anymore if he did not have to pay for a roof over his head and food.
Not a great choice-------like being between a rock and a hard place.
But these were parents-------and he was a child.
And this was the best solution for the time being that the parents could come up with.
And eventually, that child did get help......and still goes to meetings...... and is almost 20 years sober and clean.
Other people find that if their spouse is truly sober and going to A.A. and is really committed to staying sober......but is having terrible times with toxic withdrawal and can't "get it together' in their brains enough yet, to keep a roof over their heads.......then the spouse may choose to help them out financially.
Now, this is VERY individual.
Sometimes, when we do that --------- help them out with money----- we could kick ourselves afterwards, if we are not living with them and they wind up having sex with other people....in the room that we paid to keep a roof over their heads.
So------- it is VERY individual..........
