Tony and Alisa DiLorenzo of One Extraordinary Marriage have great podcasts about marriage. During their 14 years of marriage they have struggled through many high and lows with such things as pornography, the loss of a child and financial struggles. But they keep relying on God to bring them through each challenge. In their podcasts they share very openly about both their past and current challenges and refer to lots of good resources.
[Warning: Be cautious about listening to the podcasts within your children’s hearing because they do handle some adult subjects very openly. Those might be more than you want your kids to hear or to prompt more questions than you want to answer that day.]
