MEM -
Nice post - really. I understand your frustration and can understand where you're coming from even though I haven't been in your situation yet. The mistress comment rings true. I hope that you find what you are looking for out of the future. You do have some good experience and I like the aircraft that you have flown. Any chance that you could scratch that itch in GA flying and still be happy with both the flying and the stability of the gov't job? Recently I have been wondering about that non-flying job and flying GA when able to still keep my foot in the door. Good luck with whatever route you chose.
