I too would recommend Perfect Daughters.

In addition:
Welcome to your Crisis
Solo Partner
Anything by Lerner (Dance of Intimacy, Dance of Connection, Dance of Anger etc.)
Conscious Loving.

The Lerner books are more about women. The other three are "gender neutral" but still quite useful IMO.

If your wife is alcoholic, or the child of an alcoholic, or if alcoholics, try:
It will never happen to me

Good luck. It is great that you want to learn about W; don't forget though that you can only change yourself.

Hugs.
