Douglas: Catherine 'has her own issues'

Michael Douglas loves Catherine Zeta Jones, but she has "her own issues".
The Hollywood couple's 13-year marriage has weathered Michael's throat cancer ordeal - which he was given the all-clear from in 2011 - and Catherine attending rehab for Bipolar II disorder twice, but friends say dealing with these things has taken its toll on their marriage, which they announced earlier this week they are taking a break from.
