I like Gottman. I have one of his books and was thinking of getting "What Makes Love Last?". Let me know what you think when you have digested it.
Have you had to deal with icy indifference and silence from your wife. I would love to know how you might handle it. I remain neutral and try to ignore it. I think I give off a nervous vibe when I talk to her. I sometimes get apologetic when I feel the dreaded eye roll coming.
