I know this situation happens all the time and more eloquent and better writers have described this type of situation much better than I, so I won't recreate the wheel here.
But it is so disappointing, nonetheless. One can't help but be a little heartbroken.
So I am running away from home for a time. There are new classes and new milongas and new people to meet.
I just hope that guy will be a little sorry, but frankly, I'm sure he won't even notice I'm gone.
