Tomber amoreux a Paris

How do you justify feeling so strongly about a person you've only just met and barely know? Everything I'm feeling is just mixing inside of my like a chemical explosion waiting to happen. It's so hard to act like I don't care (and I know for a fact I'm doing an awful job even pretending). I wear my emotions on my face like an open book. If I'm feeling it, the whole world knows. And now I'm sitting alone in Paris trying not to cry because I'm way to involved in a relationship that's going no where with someone that doesn't even like me! Yes, I brought this on myself and I let it happen, but now that I want it to stop I just can't think of what to do. Oh great, the object of my obsession is sitting in front of me. Shoot me now. -.-
