Excerpt from my latest Sasstrology article (Please comments on the Sasstrology site):
"Nodal contacts in synastry create a powerful draw between two people. Most powerful are conjunctions between one person’s planet and the other person’s North or South Node. The inescapable, fated connection can be wonderfully overpowering. But sometimes, the exact thing that magnetizes two people can also end the relationship. As profound as Nodal conjunctions are, if these contacts are not handled with care, they can lead to a permanent break."
