Easier said than done when you're in a really sticky situation, or just struggle to say stuff. Besides, I hate arguing; it's stressful and unnecessary. If I only need to just not say whatever it is, then that's a job well done; it might not be ideal, but gives me less grief, and in turn, her. If, however, it's something so bad that it festers as you say, then yeah, definitely a problem, and it would come out, but small things that don't matter? I'unno. I'm all for good communication, as well, but maybe good communication doesn't have to mean communicate absolutely everything that crosses your mind? Especially if you have OCD/anxiety like me and think all sorts of whacky stuff. xD
