I'm not bulletproof

Ever felt like after giving everything into someone or something, that you're left with nothing in the end?

Ever had someone say they loved you, and that if nothing else they'd always be your best friend, only to have them disappear off the face of the earth?

I've always thought of myself as an eternal optimist (for the most part) and of course a hopeless romantic, and at the same time apathetic to the point that when my optimism turns out to be wrong, it doesn't bother me in the slightest.
Only once in recent memory has the above been untrue, and I can't quite shake it. Yet, I also feel like I'm ready to move on and leave it all behind. I just feel like there's some unfinished business, and I suppose some 'closure' is needed. Sorry for being vague.. details are available upon request?

On a side note, I suppose the apathy stems from years of suppressing most any emotion, if you're never too high, you can never get too low was my take on it. I'm sure my various insecurities have a part in it as well, but what can ya do? There was more to this but I've completely lost my train of thought.

Now if you'll excuse me, I'm sunburned and have some drinking to attend to.
