Better to have loved and lost than to have never loved at all.
False.
It felt much better when it never existed, because then I wouldn't have known it in the first place. Better is qualified as being in a state of existence at present that is more desirable than the past. Before the love you were fine, afterwards you are sad. Not only that, now that it is gone, the whole time in between was a waste and you might as well have never had it in the first place and could have been much better off doing something else.
Truth?
It's only better to be in love, than not at all. Of course you can't expect all love to never end. But it still doesn't make it better when lost.
