no one here can tell you if he will change or not
you have the power to help him
you never know what ya got til its gone and you did the right thing
hes scared hes gunna loose you now
id stand your ground and say youll be there for him as a friend for now and when he shows you hes sober or when he takes AA classes or something then youll go back
but for now stay strong girl-
it can either get 10times better or 50 times worse
best of luck
