You might think that you're just offering support and good advice when you push your lover to get proactive about their career, but this could actually come across as too controlling. You might not even understand their work -- there is a disconnect between what they're actually doing, what's important to them, and how you perceive their work. You tend to misunderstand their motives and consequently, you give them advice that's moot.
This is like pressuring a scientist to advertise their findings when the study is only halfway complete -- it is just missing the point, and feels like unwelcome pressure. Instead of letting this happen, as it could end up damaging the feeling of support and trust between you, you should instead try your hardest to take a hands-off approach to your partner's career. Lend a shoulder or an ear when it's needed, and try to listen to what your partner is really telling you about what they're working on and why. Beyond that, hands off!
