When your Loved One is coming home, it's time to collaborate and negotiate about expectations and plans. It's important to hear what consequences they suggest for certain actions or inaction, and to keep communicating openly over time.
This is a ripe moment to have a talk about the various possibilities and what might occur in the near future. This is a PERFECT time to use the leverage you have (they want to come home, they are not currently using substances).
The CRAFT model that we teach at alliesinrecovery.net is a therapeutic process that teaches us how to be in relationship. Shift your loved one's trajectory with substances and recovery by shifting your own patterns.
