My girlfriend says she's a free spirit and I don't know what that means. Can you help me?"?

it seems that my gf always has friends that she’s attracted to which in turn makes them respond to her. She tells me they’re interesting and cool which they are but her attractions to them makes it very hard to believe its just friendship. we argue over this because she feels i dont have an open mind. she treats me like i just dont want her to have friends at all. I never told her to not have any friends but i have told her that just becuase she finds people attractive dont mean she needs to flaunt that in my face by befriending them. I told her i thinks she wants me to rest on her word alone while she goes on mini dates with “friends”. its like she sends these signlas to these people and they respond and when i say something she pulls the trust card. when i asked her how would she like it if i told her every person i met i found attractive and then they ended up at the dinner table? she just blew me off and implied i was closed minded. because i havent caught her actually cheating she feels im paranoid. when i mention that cheating isnt sporatic but builds up she says “just becuase she bought someone a bear that she attracted to doesnt mean anything or just becuase she has a topless pix in her phone of someone that likes her doesnt mean anything”. then she says its my perception. If i was to write a quote for her friends, to sum up the vibe of it, it would be “i know what your thinking but it isnt what it looks like/seems”. bottom line, she dont want me to judge her friendships. she says i dont trust her but i do. I just dont trust her logic, her reasoning. its like the only too far for her is cheating but everything else is perception. when i asked her if she wanted to be with me because it seems she wants to be single but not alone she tells me if we were going to break up we would have by now. So, America, i love her completely but she fights to the death for her freedom to do whatever she wants with her friends. I’ve never cheated on her nor given her a reason to. She feels attacked when i confront this so i dont even deal with it anymore. now i feel like as her lover i cant even communicate w her. Help fluther-she might be gone with the wind
