Divorce is just a tool, and it can be used for good or for evil. Christian women need divorce because the church is no longer teaching Biblical marriage where a husband loves his wife as Christ loves the Church. If a husband in any way lacks dominance or attraction, then Christian women absolutely must learn the power of divorce.
Because divorce is morally neutral, then we can apply it judiciously. Christian women don’t need to go whole hog divorce, but what’s wrong with a little seasoning? Start lightly; maybe pretend you have a headache tonight, and withhold sex from him.
Divorce is truth: Thousands if not hundreds of thousands of women have encouraged their man to get some skills in attraction and dominance by withholding sex, divorce, and the efficient use of adultery. What’s wrong with her flirting in front of her husband if it causes him display a little manliness? Even if things don’t work out between her and him, she will have left him better than she found him.
If this is wrong, explain why in the comments.
