I realize that this is an Eastern Orthodox board, and that I'm a guest here, so I'd just like to throw this out for interest's sake, not by means of judgment or argument. This one of the big issues that divide the Eastern Orthodox and the Oriental Orthodox. In the OO Church, a divorce will only be granted in the case of adultury (ie one spouse has intercourse with someone who is not thier spouse), and only after attempts at reconciliation have failed. Substance abuse, abuse, workaholism, etc, are not acceptable reasons. In the case of abuse it is common for the couple to be separated, and often the abuser will then seek marriage in another Church and the abused will then be free to remarry if they chose, although many do not. In my limited understanding, the reason for this is that it is sex which completes the union between the two, which completes the process of making them one flesh that is beguin by the coming down of the Holy Spirit at the Liturgy. Sex is a powerful source of unity for the couple, and of blessing from God. Sex is also the thing which has the power to break the bond between spouses that it creats, when it is misused in adultury. It is the one thing that has the power to make the two one, and to make the one two, through sinful misuse. So it's not that we say that the abused party for example should stay without their spouse as punishment or because it's fair... but because they consented to become one flesh, and whatever the consequenses to has literally be done, and we cannot chose to undo it. Many people lead full lives, close to God in separation without receiving divorce to be able to remary. Remarrying if the other couple has not commited adultury is in itself adultury since the two are still one flesh.
