You have asked a good question and it is one that I can give you a Bible answer for. As to how it applies to you personally I could not give an answer without knowing more. The purpose of my article is to comfort those who are hurting with the hope they would build their faith and serve God. Wherever you find yourself, there is a path to serve God, especially if you have sinned in some area (all of us are in this category!). 

First, to the general question of divorce, someone has sinned when a divorce occurs. Marriage is for life, “till death do us part” as is commonly stated in our marriage vows. Consider the broader context of the quote from Jesus in Matthew 19:

Matthew 19:1 through Matthew 19:9 (NKJV)
¹Now it came to pass, when Jesus had finished these sayings, that He departed from Galilee and came to the region of Judea beyond the Jordan. ² And great multitudes followed Him, and He healed them there. ³ The Pharisees also came to Him, testing Him, and saying to Him, “Is it lawful for a man to divorce his wife for just any reason?” ⁴ And He answered and said to them, “Have you not read that He who made them at the beginning ‘made them male and female,’  ⁵ and said, ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh’? ⁶ So then, they are no longer two but one flesh. Therefore what God has joined together, let not man separate.” ⁷ They said to Him, “Why then did Moses command to give a certificate of divorce, and to put her away?” ⁸ He said to them, “Moses, because of the hardness of your hearts, permitted you to divorce your wives, but from the beginning it was not so. ⁹ And I say to you, whoever divorces his wife, except for sexual immorality, and marries another, commits adultery; and whoever marries her who is divorced commits adultery.” 

The statement in verse 6 is very strong: “Therefore what God has joined together, let not man separate.” In the Sermon on the Mount Jesus again addresses the subject of divorce:

Matthew 5:31 through Matthew 5:32 (NKJV)
“Furthermore it has been said, ‘Whoever divorces his wife, let him give her a certificate of divorce.’ ³²But I say to you that whoever divorces his wife for any reason except sexual immorality causes her to commit adultery; and whoever marries a woman who is divorced commits adultery. 

Divorce is allowed when one's mate is guilty of adultery. You then have a right to put your mate away.

I also recognize that divorce can come because of the actions of another. While all divorce involves sin on the part of at least one of the mates, I have worked with several Christians whose mate forced the divorce issue. The Bible also addresses this situation. In 1 Corinthians 7 the word “depart” is the same word translated “divorce” in other passages. That is the subject that is addressed in 1 Corinthians 7. Please notice what one is to do in that setting (assuming no adultery has taken place).

1 Corinthians 7:10 through 1 Corinthians 7:11 (NKJV)
Now to the married I command, yet not I but the Lord: A wife is not to depart from her husband. ¹¹But even if she does depart, let her remain unmarried or be reconciled to her husband. And a husband is not to divorce his wife.

If your mate has forced the divorce, then you have no sin. Notice a few verses further where Paul addresses the specific situation where an unbeliever departs:

1 Corinthians 7:15 (NKJV) But if the unbeliever departs, let him depart; a brother or a sister is not under bondage in such cases. But God has called us to peace.

I hope I have not thrown too much at you in answering your question. There are so many things to consider in such a question as this. It is definitely a subject that the Bible addresses at length. Sadly many churches will not teach on these kinds of things anymore. I do not enjoy addressing these matters either, but my goal is to be true to my God and teach the “whole council of God” (Acts 20:26-27). 

Most of my teaching in this area has the goal of preparing our young to choose the right kind of mate. In every place I have preached I have worked with Christians who have experienced divorce both from an innocent standpoint, and also from a standpoint where they were responsible for the divorce. I want everyone to see clearly what God has said and then to find His forgiveness and serve the Lord in a full and abundant life.   

I really appreciate your good conscience and your willingness to ask this question.
