Soulmate Emotional Destruction Theory

Ultimately the consequence of this notion is the unfortunate reality that soulmates often possess the ability to inflict serious emotional injury unto their twin flame, greater than any other being could. This often results in the separation of idealized love, due to the severe emotional impact. Many soulmates are destined for an eternal search, not for lack of meeting, but rather lack of acceptance. The encounter is often analogous to the collision of matter and anti matter, a violent explosive will occur, but if held through to completion only pure energy, and thus harmony, will result. Unfortunately few encounters are held through to completion.
