My friend, I am not sure that you have the complete information about this from the Orthodox perspective.
The Orthodox Church allows for divorce under circumstances of an adulterated marriage. If you read Chapter 19 of the Gospel of Matthew, you will see that Christ was questioned about this. He states in His answer, "And I say to you, whoever divorces his wife, except for adultery,and marries another, commits adultery; and whoever marries her who is divorced commits adultery."
It is clear that Christ is permitting a divorce if the marriage bed is adulterated. When a couple splits up, there is a spiritual trial. The result of which can be the granting of a divorce for one party in these circumstances. But just because you split up without the proper reason (adulteration) does not mean that you get to have a divorce much less remarry. If you were the one who committed adultery, and the divorce is granted against you, you will not be permitted to be remarried.
Obviously, we make every effort to prevent this from occurring, even if adultery is committed. But it does happen. If you were cheated on, willing to work it out but abandoned by your spouse, and you received the divorce in your favor, then the granting of a second future marriage is an condescension to our weakness. The second marriage service is not even the same as the first, it has a penitential theme to it, very different from a first marriage.
If you still feel that this is unwarranted, then you place yourself above the Holy Fathers of the Church, who you as a Roman Catholic venerate as saints as well, since they were long before the Great Schism. And if that is your judgement of yourself, then I cannot help you further.
