In certain extreme situations, some Christians have decided to separate from or divorce a marriage mate even though that one has not committed fornication. In such a case, the Bible stipulates that the departing one “remain unmarried or else make up again.” (1 Corinthians 7:11) Such a Christian is not free to pursue a third party with a view to remarriage. (Matthew 5:32) Consider here a few exceptional situations that some have viewed as a basis for separation.
Here is the paragragh from the book that states that the abused spouse is not free to remarry if she leaves her husband for abuse. It mentions extreme situations and then the following paragraphs classifies abuse as an extreme situation. So those are a woman's two choices.....stay and get the crap beat out of you, or leave and spend the rest of your life alone. Noooo the society is not influencing a woman's decision at all (sarcasm)
Meanwhile, the abuser after being disciplined by the elders, which may be disfellowshipping or it may be the removal of the priveleage to carry the mics, will once again be considered a valued member of the congregation after a few months and have his pick of the many 35+ year old single sisters in the cong, because he did not ask for the divorce. If I am wrong someone please correct me.
