Honestly what's the definition because I forgot once he broke my heart a long time ago......It's not just a word it's an action you do....Lying, cheating, and sneaking is so much work....Why not just do what's right? And love and hold the woman you say you love tight instead of cheating with Tanya, Lisa, and Mary but being faithful to woman you say you want to marry....I'm not preaching I'm speaking the truth....Karma comes back fast so be faithful and the love you feeling right now may last
