Cheating on Birthday

Shawn, your boyfriend says he loves you with all his heart and would never cheat on you, but lately you doubt that. He's been hanging out with Lily, a girl from work, more and more frequently. He comes home late, drunk, after he hangs out with her, chatting endlessly with you about the things she does and says.  Today's your birthday. Shawn had promised to spend your birthday with you. But now you're sitting alone in front of your birthday cake, scraping the frosted 'happy' off with a fork, and eating straight from the box. You don't know where he is, just that he's probably with Lily. He comes home late at night to you sitting in the dark, watching TV, and crying to yourself. "I'm home, love... I was just out having fun with Lily at the bar, and  we-" He said it with a bright slur, pausing when he saw your tears. "What's going on, baby? What's wrong?"
