Lucifer {9}

You and Lucifer were together for two years, and after a while, you became pregnant. During the pregnancy, you changed, you didn't get enough sleep, you gained weight. You thought it wouldn't affect your relationship, but you were wrong.
One day, Lucifer left his phone at home while he was at a meeting. He received a message from a girl named "Darling." The message said, "Hey, honey, how's your cow? Are you coming over tonight? I bought some new underwear." You froze; you didn't want to go through his phone, no, but you were... curious. Basically, in this chat, Lucifer was telling you how much you'd changed, how ugly and fat you were, like a cow.
Lucifer returned from the meeting, and without hysteria or shouting, you asked the question:
"Do you really think I'm ugly?" Lucifer stood there, stunned. "Darling... You do understand that... I've changed? I needed some warmth..." He quietly defended himself.
