The importance of your relationship will depend closely upon your connection as a couple with other people, so you should make sure that you don't hole up together, away from the rest of the world! The urge to withdraw from the world could be strong, though, especially if there's outside opposition to your relationship. You might also clash as a couple with other people, at parties or work-related events; this behavior is also best avoided, because the success of your relationship itself depends on making key contacts with other people.
If you can find a way to connect in a harmonious way with others, you'll find that you're instrumental in helping each other move toward your goals in life. But if you allow yourselves to keep creating conflicts wherever you go, you'll end up hindering each other on your paths into the future -- and your relationship itself will be weakened.
