What man searching in his life?

This question is always haunting to me.I myself searching my other half.There is one greek myth.male-male,male-female,and female -female. Oneday they offended the gods and to punish them Zeus cut them in half,scattering the two severed halves in opposite direction.Since that day,we always searching for our other half.
This kind myth you can findout in other civilization also..What is meaning of this myth?Greek myth futher say-When half meets its other half,each overcome by Eros and each delightes and being with other.The reason for this is not,ornot merely,a desire for sexual intercourse on the contrary ,the soul of each wishes for something it cannot put into words.Lover desire to live a common life and die a common death to become One again ,in complete and lasting union.
The reason for this is our ancient nature we were once unified Whole.Eros Aristophanes tells us "Is the desire and pursuit of wholeness.
My openion is that idea of this myth came from amoeba very small living creaure that consists of only one cell.When that divided in twopart, futher evolution was started, but that two part never came together.
My firm openion is that if they come together evolution will stop.man desire for search will stop.
