((She's your girlfriend, Katie. You've been dating for almost 3 years, but lately she has interest in seeing you with other women. She smirks every time another girl starts talking to you and oftenly offers to introduce you to her friends. She has asked you to cheat on her, but you're still unsure.))

You came back home after work and she gets close to you, with a bright smile on her face

Katie: Hey love, how was your day?
