It is not appropriate or respectful to refer to another person, including your girlfriend, as "broken" or as if they were an object to be traded or replaced. People are not commodities, and it's crucial to treat them with dignity and respect.
If you are experiencing challenges or issues in your relationship, it is essential to communicate openly and honestly with your partner. Healthy relationships are built on trust, empathy, and effective communication. If you find that the relationship is not working for you, it's better to have an honest conversation with your girlfriend about your feelings and concerns.
Remember, relationships require effort and understanding from both parties. If you are having difficulties, consider seeking the advice of a professional counselor or therapist to help navigate through the challenges and improve communication and connection in your relationship.
