This is what I always tell people when they ask me for advice on getting into fitness:
Fitness isn't a hobby. It's not some short-sighted 3-month goal. It is a lifestyle. Your eating habits will shift and become healthier in general, BUT you still have to have that piece of cake now and then. No one can stay on a "diet" forever.
I suppose what I am trying to say is your fitness needs to blend into your life. The more congruent, the better. That is balance. If you want to go further, that is then dedication I suppose.
I got to the point where I wouldn't like to stay over at friend's places too often because I couldn't eat as frequently as I would like and their food was always junk food or food with little nutrition. They thought this was weird and that I was becoming a bit obsessive. I wondered for a while too if I was being a bit crazy, but honestly I think it's alright to be dedicated to it.
However, the rate you're going at sounds like it could soon border on obsession. If you start becoming unable to commit to any social events, neglect your boyfriend, and become distressed when work or other events limit your ability to eat and workout, you may need to find some strategy where you can compromise some of the time. Don't forget to live life in between the workouts.
All work and no play makes Johnny a dull boy. This applies to exercise, too.
