Ephesians 5

"Nevertheless let each one of you in particular so love his own wife as himself, and let the wife see that she respects her husband."  Ephesians 5:33

I don't claim to be an expert on marriage, but I can say this with certainty...  Respect is a really, really big deal to men.  Most married men derive their value from how well they provide and care for their wife and children.  It's how God made us.  Wives, whether or not he says it, your husband lives for your respect and admiration.  He wants to be your hero.  Bearing that in mind, you absolutely have the power to make or break your man with a few little words.  One little complement about what a strong and able man you have, will send him strutting around town ten feet tall and bulletproof.  On the other hand, one little cutting remark about his insufficiencies will send him home with his tail between his legs. 

A wife who is loved unconditionally by her husband, and a husband who is respected by his wife, make for a very happy and healthy marriage.
