I echo the words of those who have already commented. Chin up and do positive things with your wife. Plan a weekend getaway, buy her flowers unexpectedly, buy her a small gift for no reason at all. Plan little things every once in a while as a family that will make them miss a meeting here and there.
My wife sounds an awful lot like your except we don't have kids yet. She is open now but it takes time.
Sadly though some may never wake up so just be prepared to deal with that. Remember all the stories the Borg says of unbelieving mates who years later came into the truth? Well your story may be the opposite. It just takes time.
