Is Abuse Biblical Grounds For Divorce?

This season on the Straight Truth Podcast, Dr. Richard Caldwell and host Dr. Josh Philpot will be before a live audience seeking to answer questions that are on their hearts and minds. The question brought today relates to Matthew 5:31-32, where Jesus is speaking about divorce. This passage seems to imply that the only reason for divorce is sexual immorality. Our questioner would like to know if this is true, is sexual immorality the only grounds for divorce, or can physical abuse of a spouse and or children be grounds as well.
