Depends what you've loved, what you've lost and how you've lost it.

And how long it lasted.

Nah...it's always better to have loved.  Provided you can always say "no regrets - just lessons learned'

I think it is better to have loved and lost, then never having loved.

Even though it is heartbreaking, painful and probably something you never get over, at least you can say that you did love and were loved back at least once in your lifetime.
