A one-sided relationship is a type of relationship where one person invests more energy and effort into making the relationship work than the other person. It is characterized by an imbalance in the effort, energy, and tasks, where one person feels like there is not a reciprocity that they would like. In a one-sided relationship, one person does more of the heavy lifting emotionally, physically, and mentally. Some signs of a one-sided relationship include a lack of deep connection between partners, feeling like roommates instead of soulmates, feeling exhausted and relieved when the partner is not around, and being the only one who ever apologizes. One-sided relationships can cause mental anguish and be physically and emotionally draining. If you feel like you are in a one-sided relationship, it is important to communicate your feelings with your partner and work together to find a solution.
