You remember the lies that you once believed, the lies that you thought were so true. You think your on top of the world because he said he truly loved you, but that was the lie. If he loved you, he wouldn't be going around kissing other girls. He wouldn't be going around making fun of you.
If he truly did love you, where is he now? If he so much as cared just a little, he would be by your side. He would sacrifice his time to be with you. Don't make excuses for him, because your just letting all the crap he is putting you through slide. Don't let him get away with calling you nothing. Don't let him get away with your heart crushed in his hands. Don't let him think its okay to break you apart and leave you in tears and pain.
Fight the pain you feel when he hurts you, remind yourself he is not worth it. Tell yourself and him also that your life is better off without him.
