Lupin's Lovesick Ladies

Just a list of ways Remus didn't keep a romantic partner for any length of time, mentioned it as a joke in my Reading the Books series, and then, how could I not do it? In no particular order of his years in school, no house discrimination though I didn't specify, and some sexual curiosity, so if you don't like the idea of at least bi Remus some of them might annoy you.
