January 25 2024- he article cites Susan South, a clinical psychology professor at Purdue University, stating that couples typically identify their differences early in the relationship, leading to either a breakup, acceptance, or ignoring the issues, which may resurface later as continual fights. While some level of fighting is considered normal and healthy, South emphasizes the importance of “fighting fair” by working toward a goal without defensiveness or criticism to help couples problem-solve and progress together. If this approach isn’t successful, problems may resurface years later, causing individuals to question if their partner is still the right person for them despite deep love.
