Only marry a true believer in the Word of GOD if you want your marriage to last long... better still, marry a woman/man of virtue.
A wife must be submissive to her husband for a marriage to work and a husband must love his wife with all his heart. This is the fact of marriage most people do not understand.
"Husbands, love your wives, and do not be harsh with them."— Colossians 3:19
"However, let each one of you love his wife as himself, and let the wife see that she respects her husband."- Ephesians 5:33
“For husbands, this means love your wives, just as Christ loved the church. He gave up his life for her." — Ephesians 5:25
“In the same way, you husbands must give honor to your wives. Treat your wife with understanding as you live together. She may be weaker than you are, but she is your equal partner in God's gift of new life. Treat her as you should so your prayers will not be hindered." —1 Peter 3:7
"The husband should give to his wife her conjugal rights, and likewise the wife to her husband. For the wife does not have authority over her own body, but the husband does. Likewise the husband does not have authority over his own body, but the wife does." —1 Corinthians 7:3-4
"For man was not made from woman, but woman from man. Neither was man created for woman, but woman for man." - 1 Corinthians 11:8-9
"Likewise, wives, be subject to your own husbands, so that even if some do not obey the word, they may be won without a word by the conduct of their wives,"—1 Peter 3:1
"Likewise, husbands, live with your wives in an understanding way, showing honor to the woman as the weaker vessel, since they are heirs with you of the grace of life, so that your prayers may not be hindered."— 1 Peter 3:7
This is the wisdom of the Creator. Time proved its perfection. Unfortunately, now people use other "wisdom" and are unhappy.
