1. Know it All Attitude: When the two people in a relationship think they know what's best for the relationship, and they are not willing to learn from each, they will both be too arrogant to listen to the other person. Relationships die because the two won't take the other's suggestion serious; they think they know more than the person they are dating. In such relationships, there is no leader, there is no peace; everyone is telling there friends how their spouse is not listening to them.
