Is that damn button bouncing yet? [/mixedthreads]
I have a little experience on two topic areas...
I dated a nurse (kind of; she was in school to be a physician's assistant). The reality of crazy work schedules never really hit, since I was dating her while she was working on her post-grad and doing internships and such.
We had gone to school near each other; regional rival schools, actually. She hung with a girl I knew from high school, and it grew from there. It was great until she went off to grad school; I was pretty misty eyed the day she started because I knew things were going to be different. "No, they'll be fine, blah blah blah..."
Sure enough. Suddenly her smarter school friends were a lot more fun to hang out with than her sportswriter fiance. She dumped me over the phone while I was in the office. "You know, I've been thinking..." she said. "Sonofabitch, she's gonna drop the bomb," I thought. "...we shouldn't get married."
Whatever. She did me a favor. I try to convince myself I have no reason to be bitter about it - more on that in a sec - but deep down inside, I still am. I guess I just never understood how a guy that tried so hard to do everything he could for her turned out not to be good enough once she moved away. But hey, she was right: It really wasn't me, it was her.
Now? I've got zero to complain about. Wonderful wife who completely gets it and understands the job. My No. 1 priority in life is spending time with her. My job takes a backseat to that; that's why I work day shifts whenever I can. I made the decision to put life ahead of work; does it mean I'll never make to SI? Probably. (Though one could argue I wouldn't have anyway.) But that's a decision I'm fine with, and I recognize it's not going to be the same answer for everyone else.
As usual with my stories, I'm not sure if there's anything to be gleaned from them, but I figured it couldn't hurt sharing.
