Samson and Delilah - Not The Epic Love Story I Thought

A few days ago I decided to take a look at the Bible story of Samson and Delilah.  For some reason I had always thought that theirs was an epic love story. This is definitely not the case.  In fact, I have serious doubts that Delilah ever loved Samson at all.  She betrayed him... multiple times!  This is a horrible story.  Why have I always been told that theirs is one of epic and unconditional love?  I thought that maybe as I read on that Delilah's mistakes would be redeemed but they were not.  I am not just surprised I guess you could say I am disillusioned and disappointed.  What other misconceptions do I have about other stories??  I am not entirely sure if I want to find out.
