Mixed messages in your relationship can be one of the most frustrating elements of communication. Whether it's about sex, love, or something in between, what do you do when you think your partner is upset but they say everything's fine? How do you handle little jabs -- and what do you do when you're the one issuing them?

Grasping the dynamics of passive aggression and how to handle things instead could just save your relationship -- or help you build a better, healthier, and more rewarding one in the future.
