This is a day of soul-growth for you, and you can do it alone or with a companion. It might not be the best time to make contact with someone new, because you're likely to get involved with people who will throw your past back in your face -- unintentionally, of course -- as a catalyst for growth and pushing forward into your future. While growth is good, it could be strange and uncomfortable to make a connection with someone new and then go out on a date with them, only to find that they remind you exactly of your ex -- or that they even know someone you used to date!
In some way, your relationships during this period are going to reveal your own past and your old self to you in some surprising ways. For that reason, it might be best to hang out with people you're already familiar with, because trust will help you to be more open to the lessons you need to learn. Now, this is not a time to hang out alone in your room, journaling or writing poetry; you definitely need social contact. It just might not be the best time to go on a date with someone special. Hang out with friends instead, and talk with them about your feelings and impressions.
