Your lover has a very strong idea of where they need to go in life, and in this particular relationship, one of two possibilities might transpire. Either you believe that your lover should help you along in your journey with their advice and practical experience; or, similarly but quite the opposite, you insist on following a path that you set for yourself long ago, actually ignoring valuable advice from your partner because you don't want to change course midstream. Either way, you both struggle as a result.
How can your partner move along their own path in life if they're always having to stop and backtrack? How can you progress along yours if you refuse to remain open to change? You might each become quite stubborn about demanding what you think you need for yourself, and your lover reacts strongly against any moves you make in a direction that challenges them, or that leads away from them and toward independence. This kind of struggle comes up between you again and again, and it is up to both of you to choose how you handle it -- or whether it's even worth it to stick with the relationship, with this kind of deep-level incompatibility between you.
