Don't let him see that you care. Act like you don't see him. When you cross paths, don't acknowledge him . When you walk past him , don't say anything , just keep your head low and keep walking . Remember that he is not going to come and hug you from behind , like he used to. He doesn't care for you anymore. When you feel your heart race as you get closer to him, take in deep breaths , plug in your earplugs and listen to your favourite playlist. Sing out loud , not caring that he is around . Wait for him to leave and then my dear , you save yourself from the heartbreak of seeing him talk about the girl he loves. You didn't let him break your heart again!!
