She responds to your texts with one word.
She gives you the silent treatment.
She keeps telling you she’s perfectly fine.
She gets teary-eyed and sniffly.
She moves away every time you try to touch her.
She is blunt and vocalizes her frustration.
She ignores you to pay attention to everyone else in the room.
She leaves your messages on read.
She gets serious and stops joking around with you.
She starts screaming her lungs out.
She posts angry song lyrics on social media.
She threatens to break up with you.
