Communicate
Most problems in relationships are a result of poor communication, or a lack thereof. When an issue arises, instead of immediately getting defensive or jumping on your partner's case, take time to listen to what they have to say, and then offer your suggestion. Sometimes, after a long and stressful day, all your partner wants to have is a listening ear. While your concerns are important, it’s also important they know that you care enough to step back and understand where they're coming from and what they’re going through. Remember, it’s not always about being right, or winning.
