In a way that doesn't tie their worth to their sexual experiences.
He didn't do that. Or rather, her worth as a person was not denigrated in any way. Her worth as his partner did possibly take a hit, though.
He's not saying "You've had a threesome therefore your a whore." He's saying "You've had a threesome and therefore may not be a good fit for me." If he's the type of guy who only has sex while in a committed monogamous relationship and wants to be with someone who feels the same way, who are you to tell him that's wrong? If nothing else, it's very possible that it's a continued source of friction where she wants to do something more adventurous in the bedroom and he doesn't (since she at least has a history of being more sexually open-minded). Good to talk it out now and find out, which is what the OP said he's doing.
I think you're putting a lot of stock in a visceral response to a jarring (for him) perception change. Now that the shock has worn off some, OP is going to communicate with his girlfriend, which seems like the appropriate thing to do.
