false sympathy
When people act like they care about you and what you're going through when in reality, they don't really give a single fuck.
Example:
P1: I'm always here for you.
P2: I don't need your false sympathy!
P1: Then okay. Goodbye bitch.
P1: I'm always here for you.
P2: I don't need your false sympathy!
P1: Then okay. Goodbye bitch.
