If your ex just came back on the scene, your heart could be in a state of confusion. You need to be careful, 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 don’t try to rebuild anything between you. If you see them again, you see them again. Don’t try to steer this thing. It isn’t going to go where you want it to go anyway.
