to be honest, i don't see his recovery as the real issue here. you sound VERY clingy and needy with someone you met THREE WEEKS AGO. this period should be called DATING not already committed bf/gf. somehow in three weeks you swooped in and "got" him a job - which is way not your job or role. that's trying to FIX someone.
i sense you are young and perhaps don't have much experience with relationships. you should NEVER be "on call" to meet anyone's need. that puts things in a whole 'nother category.........
i think you need to back way off - quit smothering the poor guy, get some air and daylight between you. take it SLOW. he's already done the blocking thing, which is not the actions of someone nearly as interested as you might be.
