Some people never fall in love. Others fall in love only once, and remain true to their beloved their entire life.
However, there is another group of people who have fallen in love more than a few times, and each time it is just as profound as the first love.
It is like...
"Better to have loved and lost, than to never have loved at all."
except a lot more often. They don't exactly fall out of love with anyone, but for some reason the relationship ends, and they end up looking for love again. It is often quite tragic, and although they have never forgotten any of their loves, it does not stop them from falling in love with someone new. In their own mind they have always been true to ALL their lovers.
As in Byron's Extracts from Don Juan: Donna Julia’s Letter
To love too much has been the only art I used;
[...]
To love again, and be again undone.
..seems to capture the heart of what I am looking for, but the term "Don Juan" does not work:
a captivating man known as a great lover or seducer of women
..neither do "Romeo" or "Lothario". These seem to focus on a man who thinks of himself as captivating, and a great seducer of women.
Is their a non-gendered expression to describe this kind of person?
