Hello Masuhanley, and welcome to SR!
I am a recovering codependent and a recovering alcoholic/addict.
I drank again after 4 years clean/sober.
I was the single parent of a 12 year old and a 2 year old.
Treatment wasn't an option for me. When I was sick and tired of being sick and tired, I drug my carcass up that long flight of steps to my home AA group and started all over again.
I celebrated 20 years clean/sober this past August.
I highly recommend you find Alanon meetings in your area. A program of recovery for yourself from the effects of his alcoholism will benefit you greatly.
Get your hands on a book called "Codependent No More" by Melody Beattie.
None of my family has chosen to work a program of recovery for themselves, and that has been very difficult for me over the years.
The best help you can be to him is to work a program of recovery for yourself.
I hope you continue to post and know you are among friends who understand.
