Both individual and couples counseling were a huge benefit to me, not so much to my ex-wife, but that was because I embraced it as a learning process and she thought she was perfect. It taught me how to be a better person and a better husband.
If he will read it, get John Gray's Women are from Venus and Men are from Mars.
It will help both of you understand how to communicate better, I know several men who read it that said they had that "aha" moment.
As sad as it sounds I know some couples who communicate by email because if you read it then it sinks in, also you could write him a letter.
Hope some of this helps, if you want to talk I will be here to listen.
