Why would a girl who has a boyfriend talk to me on social media?

I've been talking to a girl on facebook who has a boyfriend and she uses words like awh.

“Awh” is not an implication that she’s into you. Sounds like she just wants to be strictly friends and you have the wrong idea

She thinks retards are funny.

Either she is a lousy girlfriend, or her comments mean nothing.
