Do Ross and Rachel ever find out that the others were spying on them during their break up?

no i dont think they ever find out!

No, I don't think they did either. I'm just watching that episode now, its heartbreaking.

No im sure they dident

yes they did

i dont think so

It was never mentioned whether they did o not. I would assume they didn't because we never saw Monica, Phoebe, Joey, o Chandler say anything to Ross o Rachel.
