You don't need a divorce. You need to study with hubby Willard Harley's, HIS NEEDS, HER NEEDS. He lists the 5 top need of each partner gathered from data of 30,000 couples counseled for marriage problems.
White Shark probably gave the closest answer. You want affection he wants sex. That's normal. Affection is a woman's #1 need, sexual fulfillment a man's #1 need. You're emotionally stimulated, he's visually stimulated. A selfish pity-party is not the answer. Men are visually stimulated, they all look! Good luck finding one who doesn't.
A good marriage is about meeting needs. Love is an action verb not a noun. Love puts the object of affection's needs above one's own. If either of you love your children more than yourself, fix the envirnment they live in, instead of destroying it.
