Well he can do ALL the 'outpatient' he wants where you live.
There are AA meetings, practically 24 hours a day.
There are many here on this site, both here in the F&F and those in recovery from alcoholism and drug addiction, that did it WITHOUT someone else 'paying for it.' And we (myself included) have recovered.
I know personally that where you are in L.V. that Salvation Army has a GREAT FREE program as does St. Vincent De Paul. There are several 'Alano' clubs (where meetings are held from early morning until late at night) also in L.V.
I say the above, because you were 'generous' enough to give him a foothold in sobriety. Now it is up to him to cement his progress and keep moving forward ON HIS OWN.
I hope yhou have found some help for yourself, be it Alanon, private counseling with an addiction specialist, your church community, or somewhere else!
Stay strong, stay connected with S.R. and remember we are walking this with you 'in spirit' and someone is almost always here to respond.
Love and hugs,
