It's critical that you understand how powerful heroin is. It's also critical that you understand that your AH is not to be trusted. And when he says something like this --
Idk what to do, he told me he wishes he was dead and that he wants to kill himself, I'm freaking out... What do I do?!?!
-- it's an incredibly manipulative thing to do. And it's incredibly cruel. If you learn where he is and he pulls this again, call 911, for as manipulative as it is, it also has to be taken seriously.
You have some decisions on your doorstep, ones you may not want to make. And chief among them, how long are you willing to ride this out, and how much are you able to take.
Keep us posted. Please be safe.
