The way someone treats other people speaks volumes. Whether it's being kind (or rude) to waitstaff or speaking positively/negatively about close friends or family members, pay attention. "Family of origin may be the most important factor to consider," Ross said. "How someone interacts with family is something you will likely have play out in your relationship unless they're really mindful/have had counseling to keep this from being an issue. Understanding the family dynamics will give you a sense of how much, if any, drama you should expect."
Even the way your partner interacts with or speaks about an ex can be very telling. "Are they compassionate? Hateful? This is often overlooked, but truly important," Ross added. "If someone speaks well of an ex, there are better odds they will treat you with compassion. It's one way to gauge emotional well-being and emotional intelligence."
