Closure

Are we affraid of closure? When things go wrong with someone we either cut them out of our lives orwe get cut out of theirs, the result of this is a whole load of unanswered questions that if we are not careful eat away at us even if we careful those questions can have a corrosive effect. So if having unanswered questions and the silly answers to them we come up with ourselves damages us so much why don't we seek closure or are we scarred of closure and what that means.
