Naive and flirtatious girlfriend...?

My girlfriend used to be like that. But she has gotten a LOT better. The only thing that I can tell you to do is not get too jealous, its hard... I mean like REALLY hard to do, but just try! Also, let her know when she's doing it... don't school her, but just flip it on her like AS she's doing it. Like, when she's "flirting" with another guy just whisper to her, hey... while your chatting with him, I'll be over there chatting with that girl. If she says ok, don't take it as a bad thing, that means she trusts you, which is a REALLY good thing. So go wander around, keep your eye on her, but try to put some trust in her too! Best of luck!!
