After reading the previous review, I do suppose the tone changes. I didn't take notice of it much, because, as you said, it was just another cliché. It's almost expected for the writer to love whoever she's talking about.

It's very real. The P.S. ensures that. xP

I know it's not intended to be this way, but this did remind me of a certain lame, cheesy, vampiric ninja...-rolls eyes-

"2) You lie. And I believe every single one of your lies." - I just think you could've used "them" instead of "your lies".

Oh, and one more thing: "Because of you, I’ve been just another stupid, lovesick teen." - It might just be me, but I don't like the word "teen". I'd use "teenager", but...eh. -shrugs-

Well, I'm not sure what to say. This is very short so it's hard to really critique. The one thing I can really comment on is that the tone keeps changing. Does she really hate this guy or does she hate the fact that she loves him? There are some moments, like talking about the heart beating fast, that made it seem like a romance that's fizzling. But the P.S. at the end flip-flops that and leaves the reader a bit confused.

That's all. (Sorry if I pointed out only bad. It's how I review.)
