It is seldom that a woman finds the man single without any girl in the picture. Men usually have several girls that they are not really sure which one to settle down with and this requires them to go through a breakup period. All these girls are usually liked by this man because they all have different qualities that the man wants in a woman.
There is this 80/20 rule where the man has the 80% of what he needs in a woman, and then he goes out to look for the 20% from another woman to fill up the 100%. A man always feels like he wants it all and this is where the woman feels like men don’t know what they want. Giving a man a breakup period allows him to quit all the other affairs, focusing on one woman.
