FWIW, sponsors are people too, and they're not on call 24/7 ready to drop everything when you want them to.
I'd think twice before going your own way. How did that work out for you recently?
When my sponsor first started the relationship with me i wasn't allowed to know where he lived. Trust gets earned.
Do we back off when people use? Sure. First guy I sponsored went back out and died of an overdose that week. We're not inclined to think of people that just relapsed to be honest. After all, they probably didn't tell us they were thinking of getting loaded, and they certainly didn't call us before they used, but after.

Recovery isn't about people caring about us. It's about doing what it takes to get better.
