That's perfectly fine, being bitter here... Many of us are, and though we do come to our better senses later, it's good to let loose some of that rage, once in a while...

I gather someone betrayed you, and while you were proper, courtly and patient with them, they found someone else who was a jerk, and obviously got physical with them as well, while you played the gentleman and got walked over...

Many of us have that same hate, disgust, and bitterness growing in our hearts.. I know in my own case, I've been feeling it growing for months now...

I'm one of the "nice guys", too, and am gradually realizing that nice guys do finish last, and that only jerks & assholes who think with their dicks get girls in this world...
