I guess I should be looking at his actions. I was thinking him being a little distant over the last few days were because I scared him with the feelings I had expressed to him in a letter. But it also may be because he's been up for at least a week and is starting the come down.
As for him using people for money or to get his next fix, he is on disability and uses that possibly welfare and gst cheques as well as using with groups of friends, they all live in low income housing which is paid for by the government, everything is pretty much taken care of. He's also very depressed and sad, mix that with using heavily, it's kinda a mess.
