Things such as falling out of love and growing apart etc. are not grounds for divorce according to what is written in the Bible; God's ideal in marriage has always been one man and one woman for life. (Matthew 19:3-6) Sadly, however, due to the hardness of man's heart (sin), God's ideal is not always realized; divorce occurs. When a divorce does occur, as to who is permitted to re-marry depends on one's degree of guilt in the divorce. As an example, say a man or woman divorces their spouse due to the fact that they "no longer love them." In such a case they should remain unmarried or else be reconciled to their spouse. (1 Corinthians 7:10-11)

In the New Testament of the Bible, there are two instances spoken of, whereby, the innocent party in a divorce is permitted to re-marry. The first instance is adultery (Matthew 19:9) and the second is desertion (1 Corinthians 7:12-15).

Although the desertion spoken of in (1 Corinthians 7:12-15) is speaking of a non-Christian deserting their Christian spouse because they do not want to be married to a Christian, desertion is even more than that. Desertion not only occurs when one physically leaves their spouse, but in all actuality, desertion also occurs when one will have absolutely nothing to do with their spouse though still present. It also occurs when one so abuses their spouse, either physically or mentally, making it impossible, or even dangerous, to live with them.
