Please find a few short insights below.
Adam & Eve were created as one unified being. They shared a soul. After being separated they sought each other to complete themselves with their partner.
Marriage is a replay of their experience in that it is our attempt to combine partial souls into a more complete whole as a husband cleaves to his wife and she to him.
Another fundamental idea derives from the verse in Genesis that states that the relationship of a wife to a husband is a “Aizer K'negdo - a help mate opposite him”. The Jewish sages learn out a vital lesson for marriage. A wife will gladly give to her husband to make him happy when he is worthy. But, if in her eyes, he is not worthy, she will oppose him and become his ultimate critic. Ring any bells?
This idea places a great responsibility upon a husband. He needs to earn the respect of his wife if he wants their marriage to be happy. So, improving the way a wife relates to her husband will therefore require taking a look if he is letting her down. If he is, then it becomes the husband's responsibility to see what he can do better.
One more pillar: both you and your life partner were created in the image of God and deserve that you treat each other with all due respect.
With best wishes,
