As far as the drugs - think of it this way: do you want the drugs or your H? You won't be able to have both and you very likely WILL lose your H if you keep going back to them.
I think the best thing to do regarding the affection situation - do things together, don't just push him for the physical. What have you enjoyed together? See movies, volunteer, do whatever you did when you were dating and such. He will need time to trust you again, and hopefully you can find the intimacy while you find the fun parts of your R.
Stay away from the drugs, and find some hobbies instead!!!
