Hello, Heroine, and Welcome!
This truly
IS a safe and supportive place. Sometimes you may hear something you don't quite agree with, or doesn't feel good to hear, but there are years and years of combined experience here, backed up with a boatload of heartache AND successes.

You are actually right about that. You can't help as much as he needs. You are his GF/lover/partner/friend. You are not the panacea, you are not the Sponsor, you are not his "brother in arms" in the minefield of addiction. He needs to seek these helpmates out himself....when he is starting to feel better that is. The W/D of heroin is awful, he doesn't want to fail, use again and have to go through it ever again. And neither do you.
Good luck - if he's on day six, I think he should be turning the corner.
