The Qur'an describes marriage as a relationship of mutual love. Hadith encourage both men and women to be kind to their spouses. Men and women will both be accountable in the next life for how they treated their spouses. 

That being said, most of the details of married life are not specifically mandated by Islamic law. Many things are left to the individual judgment of the couple and as ethical, personal, practical, or customary matters. Technically speaking, there is no legalistic requirement for a man and wife to speak to each other (although hadith encourage men and women to tell their spouses that they love them!). Refusing to speak to someone is immature, but, of course, marriage does not always bring out the mature side in people. Anyway, I see this question has been here for some time, so, by now, the situation has probably passed and he has resumed speaking. If not, well, enjoy the silence!
