You're not one to make sudden or unnecessary changes in your love life unless it's for a good reason. You like calculated risks, not spontaneous, impetuous moves. You have to know that you're moving toward something more solid, more stable, or you won't make a move at all.
But you also have a wonderful imagination when it comes to traditional structures like romantic relationships and commitment. When you do see the need for change in your love relationship, you're both practical and innovative about making it happen. You're probably not one to try out an open affair just for the fun and excitement of it, for example; but you're also not stuck in traditional relationship values that would keep you or your sweetie from doing what either of you wants to do. Basically, you appreciate stability and work to establish it, even while you recognize the occasional need for positive change. You may end up committing to someone for the long term at an early age, because security is one of your deepest concerns and you want to make sure that you'll have it, now and in the future. But your commitment won't be restrictive to either person involved.
