^^^what Allison said !

I was reflective, for a moment on something that my grandmother told me, "it's not your responsibility to rescue them." and I'd pull that further here and say that it's not your responsibility for happiness-whatever happiness truly is.

You're there to listen and be supportive. Maybe there's some disappointment that this adult child hasn't found their path and a way out of their foggy cloud? At the same time, to me, it's affecting you negatively despite having given them all that you could to get off on the right foot-something not everyone has. Maybe they just need trials and tribulations to figure themselves out?

Not that it's not hard to watch on your end.

Sending you warm thoughts through this.
