You two may make each other pretty uncomfortable. You want to grow and change as a human being, to expand your horizons and discover yourself; but somehow, your methods for doing that clash with your partner's, and they could end up holding you back from your own journey as a result. This wasn't apparent during the early stages of your courtship; it's more a problem that has revealed itself over time.
You take two different tacks when it comes to discovery of the unknown: you rely more on your education, on the methods you've learned to seek things out intellectually, while your partner relies more on gut instinct paired with a pure rebellious streak. Needless to say, those two methods are incompatible with each other, and you may both start to feel as if the other's methods are an actual threat to your own. You aren't able to share in each other's most original ideas, because you put up walls against the ways in which you reach those ideas. You might dismiss your maverick partner's ideas as foolishness, simply because they haven't been substantiated in a way that's understandable to you. And they may not trust your reliance on books and the more formal avenues toward learning. You must learn to respect each other's methods and listen to each other, and only then can you both have your own brand of brilliance to bring to the table.
