Try to avoid couples traveling together, and it's also best for romantic partners not to travel together lightly, because travel is fundamentally different from daily life. During a trip, people will face many situations they haven't experienced together before, such as itinerary arrangements, unexpected situations, and various trivial problems. These all require both individuals to constantly make judgments and handle issues. In such unfamiliar and ever-changing environments, differences in problem-solving approaches, decision-making habits, and emotional reactions are amplified, making conflicts more likely. At the same time, travel can easily reveal a person's true character and underlying traits that are not easily exposed in daily life, allowing partners to see sides of each other that are usually hidden by daily routines and familiar surroundings, which can impact the relationship.
