[Mr. Douglas]

Men hate it when their wife changes.
Women hate it when their husband doesn’t change.

[Night Hides Not]

Very well said. The way I've turned that phrase is: a man will marry a woman for who she it, while a woman will marry a man for what she thinks he can be.

...or somesuch...I think I like your version better.

[PLMerite]

Women marry men expecting them to change.

Men marry women hoping they won’t.

[Flaming Conservative]

If it’s one thing I learned from my first marriage, you can’t make a man change. What I learned from my second marriage -— God can.
