Set some healthy boundaries for YOU. A sample boundary would be... I like you alot, but as long as you continue using, I cannot be around you. I'll support you in your recovery, but cannot support you in your using.
Loving an active addict is a hard job, and the chaos it brings can affect your sanity and well-being. An addict will only quit when they get sick and tired of the life they are living. As much as we'd like to, we can't love them clean... if so none of us would be here. Read all the sticky posts at the top of the forum... "What Addicts Do" and "Let me fall by myself", etc. Good reading and you'll learn so much! Keep reading and posting... it will help you so much.
Sending (((HUGS))) as the path is not easy, but you're among so many who care here.
