<human>: My girlfriend of two years now has all of a sudden gotten the idea of needing a break from me.

She defines a "break" as her ability to experience the world.  I let her do absolutely everything and anything she wants to do - and she knows that.  The only thing that i do not let her do is hook up with other guys (obviously).  

I asked her to define what she wants this "break" to be for. She is telling me that she doesnt want the break due to wanting to hook up with other guys. But she avoids (maybe even refuses) to reveal the definition of what she wants this break for.

I feel like im just some little safety net in the background while she gets to fuck other guys so that if she cannot find a better relationship, she can always safely fall back into this one.

i refuse to be that little bitch "friendzone" guy that watches the girl of his dreams hooking up with everyone while he sits around and *hopes* that she will come back.  

I am nobodies bitch.

Please give me suggestions on what i should do. 

I am desperate

Can you condense the text into three sentences or less?
<bot>: Girlfriend wants a break but refuses to clarify what the intentions of this break are. I find no reasons for this break.
