I have to say loved and lost, not because I am an incurable romantic, it's more due to the fact that I believe in taking chances.
I don't think that its possible to be truly happy unless you are willing to stick your neck out a little, take a chance, fight for what you want.
In order to answer this question, you have to have known what it is like to love, otherwise, you aren't qualified to give an answer... right?
Humans have an unfathomable capacity to experience emotions and heal. If you get your "heart broken" there are still billions of possibilities out there. To say that "you will never love again" is like saying you will "never work again" after getting laid off. It doesn't make sense.
I believe that the romantic notion of being in love with someone so much that you can never love again after its over...is ridiculous.
People do not cease from all matters of the heart because they are so deeply wounded by a past lover. They stop searching because they are scared, romance has little to do with it.
