This is one of those things... everyone you actually meet is/was part of your life, your circle of friends, you lovers/partners.
We are the ninth advanced civilization on this planet. And we have had many past lives. Those who feel called to see their past lives are often the souls who have been reincarnated the most on this planet.

So, about love, just because you were lovers in a previous life, does not mean you will be so this life time. In fact, there are many changes happening to the energy of the planet that prevent forming lasting relationships. You, them, the planet are all changing quite rapidly, exhaustingly, and until 2030 it will continue that way.

Trying to draw from past lives to find the one, the perfect one will end in disaster in this drastically changing time. So, i suggest detaching yourself from previous attachments. They were good memories, but they are not good futures.
