Valentine's Day writing prompt

Ahh, love is in the air. Pretend that you are your favorite storybook villain and you're trying to win back the heart of your love interest after he/she found out about your villainous life or past. Try and justify your behavior to them, portraying it in the best light possible. (And you're not above outright lying, after all, you're a villain.) But somehow let your character's true nature show through in your letter/speech in a way that they themselves wouldn't recognize as being menacing or obsessive. And don't forget to add what your character will do if their love remains unrequited.
