Hi sister,
The show cause is domestic violence.
I'm not sure what you mean by 'show cause', but I assume you mean this is the reason you sought divorce.
Paul wrote in Ephesians 5:28 So ought men to love their wives as their own bodies. He that loveth his wife loveth himself. 29 For no man ever yet hated his own flesh; but nourisheth and cherisheth it, even as the Lord the church: 30 For we are members of his body, of his flesh, and of his bones. 31 For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh. 32 This is a great mystery: but I speak concerning Christ and the church. 33 Nevertheless let every one of you in particular so love his wife even as himself; and the wife [see] that she reverence [her] husband.
If your marriage was never consummated, then you did not become one flesh with your legal husband. Correctly, you have gone through a legal process to dissolve the legal connection.
Regarding remarriage, even if the full terms of your first marriage had been fulfilled, if you are legally divorced, as Jesus said in Matthew 19, with 'a bill of divorcement' (which you are), you are free to remarry according to the Old Covenant, and the law of the land.
For many reasons Christians whose marriage to a Christian has broken down, don't necessarily seek remarriage, because of what Paul said about merely separating with a view to reconciliation, in 1 Corinthians 7.
I agree with the other posters that you need to search the scriptures for yourself, and be convinced in your own mind.
Under Roman Catholic doctrine, there is no case for divorce. This means many things covered by Jesus teachings in the New Testament, and Moses' leadership in the Old Testament, are made null and void.
What the Pharisees asked Jesus in Matthew 19, enabled Jesus to address directly the issues which arise from Roman Catholic doctrine today (forbidding divorce).
In Judaism, the opposite had developed - a custom which allowed a husband to get rid of his wife on flimsy reasons, SO THAT HE COULD TAKE ANOTHER. Jesus called this adultery of the heart and challenged them on it.
However, at the same time, Jesus gave the innocent party against whom adultery had been committed by a real sexual liaison, the freedom to divorce the adulterer, AND REMARRY. (Note: in New Testament Greek, 'fornication' means every possible kind of sexual liaison. Therefore, they can occur even within a marriage, and are sufficient cause for divorce to be sought by one party.)
Most of this doesn't apply to you, and it may take more than a year for you to recover from the abuse you experienced, to become healthy emotionally, and able judge sufficiently soundly, to go forward with confidence into another relationship with marriage in mind. Having said that, a good man of God would be a tremendous blessing, and the years for childbearing are going by all this time.
May the Lord comfort you and lead you. I would add that you don't have to do anything you don't want to, least of all get into a relationship with another manipulative personality.
Seek the Lord. Wait on His timing, and keep growing.
