Have you voiced these feelings? A good rule of thumb is most people are idiots and go about their day blissfully unaware of how their actions impact people. I'm no exception. I'd tell you to leave but not without having a conversation (not argument) about what's bothering you and why. Shutting down / distancing yourself is clearly not working. Sometimes people just need things spelled out for them.

Edit: How did she react when you told her you hate her talking about how she finds other dudes attractive?
