Do girls with boyfriends flirt? If so does it mean anything?
There’s no way to know, man. If she’s the flirtatious type I think you’d know, based on how she is with other people. Just because she flirts doesn’t mean she’s doing it because she’s a homewrecker and likes you, she might just be naturally flirtatious. But you seem smart and you already know getting in between someone’s relationship is a bad idea. So don’t count her out, dude. Just sit back, be cool, and let whatever happens happen.
