The old saying about love being blind truly describes romantic love. Many who are in the midst of romantic love want to be with their lover all the time and can overlook faults, conflict, and abuse.
Infatuation is an aspect of romantic love. The scientific articles that we have read concerning infatuation report that most individuals can not sustain that type of emotional high for an extended period of time such as years and years.
A person will realize that the infatuation/romantic love phase of their relationship is declining/wearing off when a sense of disillusionment sets in. Spouses may become more critical of one another, become easily irritated at things that didn't bother them earlier in their relationship, have less patience with each other, and could be indifferent to the wants and feelings of each other. Not bailing out and communicating dreams, desires, thoughts, and feelings with one another can lead to the wonderful stage of mature love.
