Six years of romance is more than most careers (and other forms of romantic endeavors) have to offer. Unrealistic deadlines are the norm but put that fact to work for you. Missing schedules is going to happen, don't let 'em get you down. No visible end, this is known as job security. No satifaction, once you can get past the stress, some of the satisfaction will come back. Also, get a real life which should be your main source of satifaction anyway.
