Specific Situation - Divorce without Cause becomes one with Cause

This should not be filed under 'Spiritual Discussions' it should be filed under 'Extremely Difficult Spiritual Discussions'. In the realm of Divorce and Remarriage it seems that a lot of people have difficulty determining what is right and wrong because there are so many things to consider and personal feelings are so involved. I think I've heard some say that those who get divorced for the wrong reason and sit and play the waiting game (to see who is unfaithful first) then neither has a right to get married. I think we sometimes try to over analyze this and really get a way from the point. However, IF a spouse really was unfaithful but they FILED the divorce as an 'irreconcilable differences" and the government recognized the divorce then does that mean that God only sees the divorce the same way..??? I do not believe that is the case. However, this is a thing that really needs all the facts and someone who has studied it more than us probably.
