In my experince my little AD wouldn't belive me when I changed because I used to threaten and not follow thru. He is most likely not making plans because he doesn't beleive you are really going to kick him out. It is not a magic bullet, this booting them out, but at least your home would be calm. My daughter is still using, but I don't have to worry who is at my house, about the drama, or the front row seat to her self destruction. It has been really hard, but it has moved from my head to my heart and i know this is what I need to do.
