"Rob was blinded by love," a Rob confidant tells People, "and realized that Kristen's mistake wasn't something that should keep him from who he truly thinks he should end up with."
Another insider says the "heartbroken" actor just couldn't walk away from the apologetic starlet: "He never stopped loving her."
That said, "There's still healing to do and trust issues," shares another source, "but Kristen will do whatever it takes."
That likely includes continuing to force a smile on her face as the "Breaking Dawn" promotional campaign kicks into high gear (the film's Los Angeles premiere is Nov. 12). It remains anyone's guess what will happen with the romance once the movie finally opens on Nov. 16.
