A close and intimate relationship from our point of view is defined as two people who have established momentum of seeing each other regularly. They might live together or not but above all, have built a connection that is strongly magnified by love, passion, commitment, friendship, intimacy and feelings. Conflict in this context is characterized as interpersonal, having mental or emotional problems, bad arguments or disagreements between them. To understand and explore conflict in close and intimate relationships, we will demonstrate two main theories, the sociocultural and the interpersonal.
