There are two causes of conflicts in human relationships. One is when there are difference in thought standards between the parties involved. Everyone has unique and 

different thought standards but conflicts begin when your own thought standards are right and the counterparty's standards are wrong. You would strongly believe 

that your counterparty is the reason for conflicts. The other is caused by the phenomenon of the error of psychological interactions. When two people interact 

psychologically, They express their ideas and emotions mostly activating the unconscious especially in close relationships, and perceive the other's expressions mostly 

activating the conscious. They express themselves without thinking and recognizing what they are doing, but the counterparty thinks that he or she expressed intentionally. 

Your counterparty may conclude that you don't like your counterparty. Conflicts occur when the fundamentals of psychological interaction are misunderstood by both parties.
