No se ha cumplido con ellos

No se ha cumplido con ellos
 

Does this mean has not come true for them?
In context: El sueño americano no se ha cumplido con ellos.

Yeah, that translation will work.
cumplirse = to be fulfilled/achieved

Thanks for confirming this, Rusty.
I have trouble with this form form of the Spanish passive. When I hear or read it used in a new way for me, it trips me up.

Could you say: No se me ha cumplido?

What you wrote before wasn't passive. Cumplirse is a pronominal verb.

The phrase you wrote last, however, is passive, and is a possible construction. I think one of its translations is it's not fulfilled me.

The word cumplir is translate as fulfill or complete.

For example, I wanna say, I have to fulfill with my work. (Tengo que cmplir con mi trabajo.)

Or it would be translated of this way, I have to complete with my job.

Thank you for your suggestion above.
