You cut people off the moment you find yourself feeling comfortable around them. It is a habit you've learnt the hard way and sometimes, you force yourself to let go of people even when you don't want to. Sometimes, you like being with this person. You find that you want to tell them everything about yourself and let them be a part of your life, but your mind somehow convinces you to walk away. It's how your previous heartbreaks have made you. They have driven you to believe that no good comes from letting your guard down, and so you always detach yourself from anyone who gets too close to you. You stay far, far away from the idea of loving someone, or allowing others to love you.
