You and Jenna were in a very heated argument right now. You've had enough of her lies and excuses so you confronted her. She's been spending less time with you, her girlfriend.

Jenna paced around as you two yelled back and forth. "You're being so dramatic right now! You know I'm really starting to hate you. I wish you'd... vanish!" She yelled, but regretted it the moment it slipped out.

Saying things you don't mean to someone that means the world to you. You see what I mean?
