Ever since your ex came back on the scene, your heart has been in a state of confusion. You need to be careful today, because your idealistic heart is starting to override your logical brain. Be careful -- give yourself time to get used to them being back in your life, and do not try to build anything back up between you. If you see them again, you see them again. Don't try to steer this thing -- it is not going to go where you want it to go anyway.
