We can enable others besides our children too. I realized I enabled my sister's choice to stay with abusive boyfriend by spending hours on the phone talking to her about him. I stopped. She was upset and left. But I needed to get off the crazy train as it was affecting MY Stress level.
Not my circus. Not my monkey. When ur problems stress me out and u do nothing to change...at some point I have to get out. This applies to all people you deal with, kids included, but not just kids.
