He cheated on me with my cousin , 5years younger than he was!

It's been six years now. But it still felt like six seconds ago. 'Yes, I've moved on! I forgot about him years back' she'd try to comfort herself but the memories wouldn't keep still. They hit back every now and then. It hurt her how he seemed to have moved on but she couldn't, he was in the third relationship now but she was still stuck on his bitter sweet memories. Only he knew what she wanted, how she wanted it, when she wanted it, what made her happy, what she hated...everything that made her up he knew. She opened up to him like she never did to anyone because she'd never slept and dreamt he'd leave her never! He entered her life with happiness, joy and excess love and left leaving her with a pale shattered heart! If anyone told her he'd be able to survive without her she would've doubted to the highest degree. She wouldn't even hurt like this if he cheated with a complete stranger but her cousin? He'd stooped that low??
