Hi Senoritac,
It is not just in Canada that this happens. I live CA and my xah only has to pay 150.00 rent a month because he is in a program to get clean. My son that is 20 has to pay 1020.00 a month for a studio apartment. My xah will use the system that is helping him only to get high again and again. I am hoping this time around he learns. Only time will tell.
If you are not ready for your x's freedom, then that is your feelings. You have the right to be afaird, but you can not worry about him. Keep a safe distance and be there has a friend and a friend only.
