Fatalist

I'm a fatalist.

Don't be such a fatalist, Tom.

....it is that, with every day, my love for you increases—though that would seem to be almost an impossibility. Why should I not become a fatalist? Remember how, on the third day that we ascended the Shlangenberg, I was moved to whisper in your ear: 'Say but the word, and I will leap into the abyss.' Had you said it, I should have leapt. Do you not believe me?"

“Maybe the problem is that you’re a romantic,” says my former lover-slash-friend-slash-male-sensitivity-reader. “And maybe so are the other fatalists.”
