"Help! I Want To Make Love With My Husband's Best Friend And Can't Resist Any Longer" 

Dear NGLatest,

My husband and I are happy in our marriage. We have
two little girls and a satisfactory sex life. Lately however, Ive found
myself lusting after other men, particularly my husbands closest friend
whom I have been fantasizing about. Hes recently been separated from his
wife and I find myself thinking about him all the time. I even become
jealous when he talks about women he fancies. Is this a symptom of
deeper problems in my marriage? Im thinking of having a bite of this
particular forbidden fruit!

Readers, what would you advice our dear friend?
