Why did my girlfriend favorite this tweet?

[john]

My girlfriend wasn't talking to me today for some reason. I later saw that she favorited a tweet that said "if you favorite my tweets, I expect you're down to makeout". I know this guy has direct messaged her on twitter before but I'm almost positive she did not reply to her. She doesn't know him in person she just follows him on Twitter and he isn't famous either he has around 400 followers.

You need to break up with your girlfriend she's playing games and she's deffiently down to cheat & she's probably planning on breaking up with you soon

She might have just meant it as a "haha yeah I like making out" thing. My girlfriend does stuff like that all the time and she hasn't cheated on me...
She just likes making out...

It's a weird situation though, because if you ask her, she'll probably think you're being controlling/paranoid...

She could like making out or she could end up cheating. You could never know.

Omg Leeroy? what a kind of girlfriend do you have it's ok to date? She cheats on you that's clearly!
and you that asked that question I would break up with her because it's not good to play the jerk
when she's the one to play the role not you Good Luck
