If Sam and Freddie broke up and he got together with Carly, she would wonder if he ever truly got over Carly when he was with her, or if their entire relationship was a lie. Every time she sees them together she'd be reminded of that. Even if Sam gets over Freddie, doesn't mean it wouldn't hurt her to see him running back to her best friend.
