Robert Pattinson -- Passes on Blasting Kristen Stewart for Cheating Scandal

Exclusive Details

The interview just aired ... and RPatz pretty much came to one conclusion -- he needs a publicist asap. But like we told you, he still did NOT bash Kristen.

While eating pints of Ben & Jerry's, Jon joked with Rob ... "Boy, you are better off, kick her to the curb!"

Stewart buttoned up the convo by saying, "When you are young and you break up it's powerful and you feel like the world is ending. This is first time I've seen the world actually react that way. It's insanity." Well said.

Robert Pattinson
took the high road in his first interview since Kristen Stewart 'fessed up to cheating on him -- because he did NOT publicly tear her a new one for the scandal.

Pattinson just finished taping his 'Daily Show' interview with Jon Stewart ... and sources in the studio tell us RPat seemed anxious about answering the inevitable Kristen Stewart-Rupert Sanders affair question.

But Rob refused to rip his ex-gf. When Jon Stewart asked how he's holding up ... Pattinson said something to the effect of, "I intend not to say anything."

Jon didn't press further, saying ... "I wish you the best, these things happen when you're young."

Outside the studio ... some of RPat's fans actually booed him as he entered, because his SUV limo pulled in without stopping.
