It is often beyond a case of wondering why you don't have your own when those around you do. It has everything to do with the fundamental design in the spiritual realm for the Lordship that was bestowed upon the man to 'father' and pour into you, that is missing. An innate sense, a imprint within your blood through their gene that constantly reaches out with a hope to be embraced.
The role of a father compliments that of a mother and vis a vers. God is TRINITY and embedded this threefold connection into the family system... and many other world systems if you think about it. The fatherless feels the absence of the Head in the equation, a discord that causes them grief.
