welcome to SR. so sorry for what brought you here.
you are among friends. you are among others who know what you are going thru and what life with active addiction is all about.
i'm a former addict and from what you have shared your AH is using, no doubt about it. the pills, the money, the lies, the deception. if he didn't have anything to hide, none of this would be in your world. your own husband stole money from you.
to be blunt - it's not as bad as you fear - it's worse. 40 pills is a lot. to have as a stash. he's not getting those from a physician. it might as well be an 8 ball of coke, or a bunch of heroin. hydros can range from $5-$20 a pill. 40 pills at the low end is $200. high end $800. he ain't saving 'em - he's using them - daily. more than........
you deserve better. you are not responsible for changing someone who stole from you, lied to you, disrespects you. that is not love.
