Well, I grew up in conservative/fundamentalist Southern Baptist churches in the deep south and throughout the midwest, and divorce was definitely preached as a sin against god and 'not allowed' in all I attended. You can't be a Deacon if you're divorced, or a sunday school teacher, or any kind of church leader. They preach/ed that to remarry after divorce is an even more grevious sin because it's adultury on top of divorce, so from my estimation it qualifies you for the next level of hell or something

.
If the wife is getting beaten by her husband, the churches I went to preached she should become MORE submissive. She should bring the issue to the church leadership, and they will pray for god's leadership to guide/speak to him. She should bring her husband to christ by her own virtuous following of Jesus, and pray for him without ceasing.
When I was in a terribly abusive and violent/explosive marriage I went to our church for help to leave him and be a single mom. I was told to pray for the lord's wisdom to guide me back to my husband and our marriage. I was told THEY would pray for the lord's direction in how to best help my husband lead our family. I was also told to pray for my husband during this time of turmoil for HIM.

I asked for money to help pay our bills as he was unemployed and refused to seek disability. I was told they needed to pray about that since I wasn't following my vows by seeking to end the marriage, they felt assisting me to sin would be inappropriate without god's direct guidance in the matter. I asked what there was to pray about? I'd tithed obediently my ENTIRE life, spent my entire marriage trying to attain Proverbs 31 'perfect wife status', taught sunday school for years, volunteered in the youth programs and the awanas programs, even when we didn't have food on our table I managed to give to the church, and yet when I need a few measly hundred bucks to get through the month they can't manage?? Keep in mind this was a multiMILLION dollar megachurch with glossy color photo spread bulletins each sunday and etched glass on each window.
I was counseled that by accusing my husband I was showing lack of faith in him as the head of our family. I pointed out he was breaking the law by abusing me and our children. They recommended some books about being a dutiful and submissive wife.

Here's the bible verses used to justify their belief...
Genesis 2:24 Therefore a man shall leave his father and mother and be joined to his wife, and they shall become one flesh
Gen 3:16 (NKJV) To the woman He said: "I will greatly multiply your sorrow and your conception; In pain you shall bring forth children; Your desire <shall be> for your husband, And he shall rule over you."
1 Cor 11:3-10 (NKJV) But I want you to know that the head of every man is Christ, the head of woman <is> man, and the head of Christ <is> God.
Ephesians 5:22 Wives, submit to your own husbands, as to the Lord, {23} For the husband is head of the wife, as also Christ is head of the Church; and He is the Savior of the body.
Colossians 3:18 Wives, submit to your own husbands, as is fitting in the Lord.
Eph 5:23-24 (NKJV) For the husband is head of the wife, as also Christ is head of the church; and He is the Savior of the body. {24} Therefore, just as the Church is subject to Christ, so <let> the wives <be> to their own husbands in everything.
1 Pet 3:1-6 (NKJV) {1} Wives, likewise, <be> submissive to your own husbands, that even if some do not obey the word, they, without a word, may be won by the conduct of their wives, {2} when they observe your chaste conduct <accompanied> by fear. {3} Do not let your adornment be <merely> outward; arranging the hair, wearing gold, or putting on <fine> apparel; {4} rather <let it be> the hidden person of the heart, with the incorruptible <beauty> of a gentle and quiet spirit, which is very precious in the sight of God. {5} For in this manner, in former times, the holy women who trusted in God also adorned themselves, being submissive to their own husbands, {6} as Sarah obeyed Abraham, calling him lord, whose daughters you are if you do good and are not afraid with any terror.
Prov 31 (NKJV) {10} Who can find a virtuous wife? For her worth <is> far above rubies. {11} The heart of her husband safely trusts her; So he will have no lack of gain. {12} She does him good and not evil All the days of her life. {13} She seeks wool and flax, And willingly works with her hands. {14} She is like the merchant ships, She brings her food from afar. {15} She also rises while it is yet night, And provides food for her household, And a portion for her maidservants. {16} She considers a field and buys it; From her profits she plants a vineyard. {17} She girds herself with strength, And strengthens her arms. {18} She perceives that her merchandise <is> good, And her lamp does not go out by night. {19} She stretches out her hands to the distaff, And her hand holds the spindle. {20} She extends her hand to the poor, Yes, she reaches out her hands to the needy. {21} She is not afraid of snow for her household, For all her household <is> clothed with scarlet. {22} She makes tapestry for herself; Her clothing <is> fine linen and purple. {23} Her husband is known in the gates, When he sits among the elders of the land. {24} She makes linen garments and sells <them>, And supplies sashes for the merchants. {25} Strength and honor <are> her clothing; She shall rejoice in time to come. {26} She opens her mouth with wisdom, And on her tongue <is> the law of kindness. {27} She watches over the ways of her household, And does not eat the bread of idleness. {28} Her children rise up and call her blessed; Her husband <also>, and he praises her: {29} "Many daughters have done well, But you excel them all." {30} Charm <is> deceitful and beauty <is> passing, But a woman <who> fears the LORD, she shall be praised. {31} Give her of the fruit of her hands, And let her own works praise her in the gates.

So, yes, there are a LOT of churches that teach divorce is a sin and therefore not acceptable, even in cases of abuse.
