What happened?

Today I got an e-mail from a friend I have known since college days. He and his wife are getting divorced. They've been married almost as long as Bob and I have. We took our oldest daughter to their wedding when she was six days old, so that means they were married almost 27 years. The news came as a complete surprise to me. But I know it's hard to know what's really happening in a relationship when you only see them once or twice a year. Still -- 27 years and now they've split up. I don't know the circumstances, I don't want to take sides, I just want to pray for them and for their grown daughter who must be hurting so to see her parents separated. I'm very sad for them today.
