Grits make sure none of what this person does effects your striving for sobriety or sanity.
I'd make sure that i had firm boundaries with someone who was still using / drinking like only meeting them at meetings or chatting to them when they are sane and wanting sobriety and willing to listen .
Stay stong and focus on your health and well being , how much is this person helping YOU ? and how are they making YOU feel ?
A strong sober happy Grits will be able to help lots of people in the future
Don't martyr yourself upon someone elses addiction , you got enough to deal with .
Bestwishes, M
