If you two become intimately involved, this aspect will go a long way toward making your relationship last, because each of you already knows that you work well together long-term. You've had practice at it already, in a prior lifetime, when you were business partners with a successful venture that lasted for many years. You may also have been involved romantically in a well-functioning union.
Either way, you created positive karma together that has carried forward to this life, and now you are once again positioned to help each other out -- to bring a grounding influence to each other's lives and create a relationship that can be a safe, steady, solid haven for each of you to come home to. Your partner will look up to you, as you have plenty to teach them about life -- about accepting responsibility and taking their duties seriously, and giving earnest thought to the kind of person that they want to be. To return the favor, they will remind you not to take life too seriously. As long as you both make sure to keep the lines of communication open between you, you'll be able to meet any obstacle with grace and practicality, as a team.
