I’ll take a stab at this. Having recently graduated from college, I am assuming you are in your 20’s - still “young”. What you are getting a glimpse of is part of the greater picture/quest of happiness: acceptance of yourself.
First, people fall into every combination across the spectrum: some “are” their jobs/careers, and to some their jobs are merely a means of income. Secondly, where one falls in this spectrum can change over the years. You may be a passionate work-aholic for years, but then decide there’s more to life and want other aspects of your life to be of higher priority.
I see the situation you are in as not feeling “equal” so much as being jealous of your boyfriend’s situation. He has a job he is passionate about, and he enjoys putting the time into it. You do not feel the same way about your own job, so you are jealous of his situation. However, it is not uncommon that he may start to rank your relationship lower compared to his career, and this may not be acceptable to you. Just because he’s into his job, doesn’t necessarily mean it is a good thing for you two (many are the marriages where one spouse is a workaholic, and the other suffers from the lack of much of a relationship - though their lives are very comfortable).
But back to the “self acceptance”. It is more important for you to compare “overall happiness” than just one aspect - your careers. For instance, you may be passionate about something not related to work (a hobby, reading, participating in a sport, whatever). And that makes your life fulfilling and enjoyable. Don’t feel that you must get this sense of “who you are” solely from your career/job. Again, you may be on a different point on that spectrum (and chances are, you are).
Now if you don’t feel that your life is so great/enjoyable, it may not be just your lack of enthusiasm for your job. And I would recommend looking into doing things that do interest you. The point is, if your career doesn’t excite/motivate you, you don’t have to force yourself to make it so. There’s a lot more to life than just working.
Most importantly, although hardest to “get”, is that only you know what will make you feel “accepted” to yourself. Generally “keeping up with the Joneses”, or comparing yourself to others, is not the way to determine this. This is what the “keeping up with the Joneses” phenomenon is all about: the Joneses will always be happier simply because they don’t care. But if you are basing your happiness/acceptance on how you compare to someone else, you’ll never really get there - it won’t be sincere/genuine.
Put another way, when you start doing things you are interested in and are passionate about, you may step back and notice that you simply no longer care how you “compare” with anyone else. You’ll notice that you’re just doing your thing and are enjoying it.
