We all at one time or another have been in a relationship where the connection has been on at time and off at times. The off times of the relationship were times that brought about a rift in the connection. No relationships are going to be without it's challenges and disagreements. It's ok to disagree but mature individuals learn how to disagree without being disagreeable. Immature individuals disagree and either call it quits or part ways with much animosity and hostility.
