I think one of the most important aspect in this discussion of marriage and divorce is the fact that Yeshua states "in the beginning it wasn't so, but because of the "hardness of the heart" it now happens".. Should we also show "hardness of heart" to those who are going through it, been through it and moved on,... As I see, it is a forgivable sin, and while the best of intentions were made by a believer, we should not crucify them, if for sin, it fails. All sin is forgiven, except the sin of blasphemy.
While the institute of marriage is the very backbone and fabric of a sustainable society, we must take into consideration, we are in the last days when there will be lovers of themselves, greedy, vile, cruel, and unnatural behavior in all forms that tear the society apart. Let us not be a party to not showing love and understanding to those who are going through the tough times, offering forgiveness rather than hitting them over the head with shame, condemnation, and sentencing them to a loveless life. I know many have tried to reconcile love and forgiveness with scripture on this subject. But I believe in this case, we are going to have to, while upholding the ideal, be compassionate with those whose path is not perfect a life without condemnation coming from our theology. As hard as that is, it must be understood there is more righteousness in grace and forgiveness than in the letter of the law.
