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

People always say this phrase (it sounds catchy and all) but is it true? Long ago I used to think it’s better to have loved and lost but lately I’ve been thinking that I wouldn’t be able to bear life without my SO and would just find my future, therefore, incomparable (and I know one flutherer in that kind of a situation right now). Would I rather not have experienced those years with him?

If you have never loved, do you want to be loved? Even at the risk of losing the someone you love?
