You could go through one or more breakups during this one-year transit, but don't be discouraged. There are relationships in your life that no longer speak to who you really are, and to hold on to them would be nothing more than hubris. You're at a threshold in life, one that you're prepared for even if you don't feel like you are.
This period of time can seem upsetting and chaotic, but if so, it's only in answer to your internal struggle to stick with the status quo. What's so great about the status quo, anyway? It's much better to change and grow, and you're in a wonderful position to do it -- you have a whole lifetime of experience and wisdom to draw from. So if you do form a relationship with someone special and then end up breaking up, take it as a sign that you were subconsciously trying to repeat old relationship patterns -- never a good idea. Take a look at your love life, at its ups and downs over the past few years; you probably will see a pattern. Take the opportunity this period offers you to move past those old, outmoded behaviors and find a new way to connect with people.
