Lanzo, I've read one of Alter's marital books, and found it helpful. It's a good read for men as it offers concrete advice--like a brother or father hitting you over the head with a newspaper. It basically advises men to be less self-centered and more focused on being selfless for their W's--good listeners, etc..
I agree with what he says, except that I would balance it with the GAL, keeping a balance of self-care and service approach. I'm sure the author would agree--he believes that marital problems are a result of egocentric husbands who need to mature.
