Hi Brightlights, I'm glad you came back and I really hope you will stick around. Support is really important right now.
I also hope you return to Al-Anon, I read your previous post about when you attended before and it seems like you got a lot of comfort there?
Have you read Codependent no More by Melody Beattie? It's a book that is often recommended here. Not saying you are codependent by the way, it just has a lot of really good information about relationships and boundaries etc.
Speaking of boundaries. What are yours? Boundaries are for us so that when these challenges arrive, we know what our options are.
If your boundary is that you will not live with a person who is in active addiction, then the path is clear, you know what to do. If your boundary is that you will give that person 3 weeks to seek treatment or they have to leave and if they do get treatment they need to wait to prove X number of months sober before returning (if you want them to return), that's your boundary.
I'm sure you have heard at least some of this in Al-Anon.
So, what is your boundary here?
