well, there is a word that some people use for people who don't have money yet still get their fix from a... "friend"... I'm sorry if that sounds harsh and I do not know your W so I really don't have friends... the unfortunate truth is addicts are so desperate, they are likely to provide pretty much anything...
Yes, tank is his full name... I think... I'll look for them.
Yes, 9's experience is a harsh lesson. From what I understand, his W is the only known suicide from this board. I truly hope is the last...
If you really don't think that your W feels you are "safe", then she is probably looking for something. I'm sure you know that. Keep any valuables tucked away if she visits.
