personally if you're dating a girl that loves to flirt, she will always be a flirt no matter what. if you get into a relationship with her, she might flirt with others guys but never do anything physical with them. she doesnt really realize that she's flirting half the time and that is her flaw. you should talk to her about how you feel because she might tell you that she'll never hurt you, but in reality, she's done it once before so what makes you think that she won't do it to you? you might be her bf now, but her ex was a bf when you two had something going on. raverboy
