girlfriend flirts her ass off with other guys. this is not just a jealous thing, our friends and the guys she flirts with tell me about this. then when I confronted her, she denied it, rationalized her actions and accused me of being jealous... I want to just walk away, but she's painting me as the jerk jealous one with the problem which annoys me to no end. She just hit me w this, I'm fired up pissed off and but need some rationale advise how to deal w this right. Do I just walk and say nothing?
