catecicc,
Hi and welcome back. Regardless of how HE is doing, YOU need to come here, to build up your strength, and find some comfort by our support.
One thing jumped out at me from your post, "His family is the primary reason he’s using"
THAT is just not true, it's another excuse to use, that's all.
Perhaps you're on the right track by saying, I didn't sign up for this, maybe think about what YOU want out of life, and where you would like to be in the next 5 years.
Addiction is exhausting...
Stay with us, find some Alanon meetings,
TRY to relax, okay..
Hugs,
