If YOU are happy and do not look to them to save you (or to yourself to save them), but give them loving, non-reactive room to work out their own destiny, perhaps listening and asking questions rather than proposing solutions to “fix” whatever you or they perceive is wrong or unhappy-making… that might just be the best way.

I don’t know if we can “make” anyone do anything, in fact.

Or if we even should. Sometimes unhappinessis part of what a person needs to inflict on themselves or go through situationally to grow and develop.

A friend calls the kind of rigorous self-care and self-soothing needed to pull off this loving by hands-off kind of spaciousness “keeping your own side of the street clean.”

Good luck.
