I think that her blog "Down On Our Luck" is her personal therapy to encourage herself to stay with her husband and at the same time a challenge that they will get over this problem.
Gambling may be very addictive but as with other addictions it has an end and it is possible to reverse the addiction. I admire people like her who has faith in love and in relationship because people like these are growing smaller each day.
They also had a very inspiring theme song, "Come What May" by Nicole Kidman and Ewan McGregor.
Great blog and keep it up... and most of all Good luck and God bless to you and your husband!
