Your future and this person's past are linked, and vice versa -- as you find out. Something in your lover's roots, where they come from, their ancestry, perhaps, ends up being closely linked to your work and where you need to go in life. They learn a lot from your stories of your childhood or your family, going back into the generations, and they are somehow able to use this to their benefit in their work.
Talking about your pasts and about your goals in life is really important, especially to your lover, because together you discover things you'd never have thought of on your own. This could even be as direct as you finding fulfilling work with your partner's family business or writing a story about someone from your life, or it could be as indirect and complex as you identifying with their past experiences and using the lessons they've already learned as a guide for your own progress forward in life. In some way, you two should definitely talk things over, past, present and future. You find that you have a lot to offer each other.
