The problem with searching for your soul mate, the supposed best option out there for you, is that it is essentially a selfish endeavour. You never ask yourself if you are the best option for them. You just take it for granted because they are your soul mate you believe you are theirs. We create an ideal partner in our minds and when someone seems to fit that ideal we assume we are their ideal and are unwilling to change to suit them. Could this have anything to do with the high rate of divorce?
