Dr. Phil episode

Dr. Phil has an episode tomorrow where a man has doubts about his daughters paternity.  They are really having a dispute about the property that was inherited.  It is so sad that families are so split this way.  I have issues with infidelity and they have come to the surface.  Will I ever get over them?  When will I stop using my Christianity when it comes to entertainment?  It is up to God how I should live my life, but it is up to me as to if I wish to follow Him and also realize that because of my beliefs and whether or not I am truly saved, I will be judged.  I have the same song playing in my head and while it is annoying it doesn't bother me.  It is all about how I react to it.  I try to ignore it but how can I ignore a thought that I would not really harm me?
