I ran across this interesting site, Happy Wives Club, and it had a good list of positive marriage quotes. An story on the founder says something that RPW takes to heart:

Weaver will not include information about what men should contribute to a marriage on the site because she doesn’t believe it is her role to tell women how their husbands should act. Nevertheless, Weaver says that women who give their best to their husbands can expect to receive the utmost love and respect in return.
