I am empathic; I understand people, so I have little need of science, I am just rather skeptical of your approach because you do seem to objectifying people, something that I have little tolerance for.
Relationships are games of a sort, but I believe that science and math have little to do with it...
Define successful relationship? Are you married? That's what I would call successful.
@Oatesy, a relationship, at least to me, is a bond that you have with anyone that requires time and effort to be spent toward strengthening it. A relationship can be friend, best friend, enemy, rival, girlfriend/boyfriend, husband, or wife. Generally only one form will exist, as others are a little bit contradictory.
enemy<rival<friend<best friend<girl/boyfriend<husband/wife
That is the order that I see it, of having a negative relationship to a positive relationship.
