Epilogue or Happily Ever After

Do you write an epilogue? Or do you just write the Happily ever After? I've been doing a little research on the differences but would like to know what other writers feel about the two. See the ending of my story will partly be a summary of what happened in the character's lives. It takes place 17 years in the future. And it is told mainly in the second person point of view.
I did find some info here http://www.ehow.com/how_5001509_write-epilogue-novel.html
But by  #4 Avoid the "happily ever after" trap. Happy endings are uplifting, but they should not be used as a way to minimize the conflict that occurred in the novel.


 I am thinking they are telling me not to change my "Happily ever after" into an epilogue.


I will continue to do more research, but I would love your viewpoints on the two.


Wishing you all a great weekend and as always, "Happy Writing"
