In most cases, we act passive-aggressively because we don't feel comfortable talking about the things that bother us.
So the next time you feel like lashing out at your husband, take a moment to understand why you feel upset. Then find a way to talk about your feelings with your husband in a calm manner. Don't be afraid to communicate your concerns to your husband because when you bottle emotions up for too long, you'll start to feel resentful and are more likely to act passive-aggressively.
