Is it better to have loved and lost or to have never loved at all?

I've always battled with this statement myself. On one hand, if you've loved and lost... You have the memories of the happiness you shared for the rest of your life, but also the memories of the pain and disappointment as well as what is gone and not there any more. On the other hand, if you've never loved at all you cant miss what you never had in the first place (which could fall under the "what you don't know won't hurt you"). I really don't know the answer to this. I for one am just glad I've gotten the chance to experience it and have that chance at this moment right now.
