Please cut your losses while you can. It is too soon in the relationship to experience all of this drama. And why would you want to be with someone who won't take you out, not even for a walk? My addict didn't take me out either, he was too paranoid and shameful, plus at home he could sneak off to the bathroom a do a bump. It's a really awful disease that takes lots of hard work to improve upon and from what I've seen, some addicts aren't willing to do what it takes to get well. Nothing will change, this man will keep you in this cycle as long as you allow it. I'm sorry, it really sucks, but you deserve better.
