My best wishes to you both. Getting started after college is both exciting and daunting.
The first job is important. I can see that Cammy's job is in the field he wants to be in. It shouldn't deter him from pursuing a medical degree. Your situation isn't bleak at all. It's not likely that you will be stuck in your first job forever. Use it as a learning experience...how to deal with other people in the work environment, how to resolve challenges. Use it as a basis for evaluating other businesses and positions. There's no reason for the first job, even if you don't really like it, to be a waste of time. It can serve as preparation for a better situation in the future.
Just be glad you don't have to face the military draft. It can be good experience, but it's the anti-choice first job.
By my count, you and Cammy have been together about five years. You obviously have a great relationship. Keep working on it and nothing else will be a significant distraction.
