It's difficult to say how this transit will affect your relationship, but it will have something to do with large, climactic, perhaps upsetting events that happen outside your bond, yet influence your relationship on a personal level. Major political events, extreme weather occurrences like tornadoes or hurricanes -- these are the kinds of things that could happen during this period, and their intensity, and the way they change how you view the world, will influence the ways in which you two interact. Your relationship may suddenly seem more important, or you could start to see it as irrelevant in the face of all the climactic events happening around you.
Remember that love and connection are the height of human experience. Don't let worldwide traumas cause you to close yourself off to these gifts of human existence.
