You've both set a path for yourselves to achieve your career goals, but this relationship could make that somewhat trying unless you can figure out how to compromise and make things work. The problem is one of mismatched energies: The way that your lover asserts themselves runs counter to the path that you need to take to reach success in your work and career. They want to help you out with all their great ideas about what you could do to improve your work or your professional situation...and then their feelings are hurt when their advice flies right over your head.
But they shouldn't take it personally; after all, you're your own person. You're doing things your own way, in the best way you know how. What works for your partner would only make you uncomfortable, and there's nothing wrong with that. If this relationship is important to you, this shouldn't be a big deal, just an occasional annoyance. As long as you gently remind your lover to step back and let you do things your way, and move toward your success at your own pace, things should be fine.
