<human>: Can you give me the gist of the text in a nutshell?

Been with my girlfriend for 8 months now and everything seems to be going well and we connect well and most of the times it's really good! 

The only issue is that she flirts with lots of other guys. I wouldn't even say that flirting is the right word, but I'm not sure how else to describe it. It's the kind of 'flirting' that gives the impression to the guy that she interested in him, leading them on almost. Most of the guys she talks to don't know that she has a boyfriend. 

For example; she had an interview yesterday and I asked if she wanted me to with her for support ect. She said no, but I went to see her anyway to surprise her. Turns out she'd already made plans to meet this other guy and wanted him to be there rather than me. (Bit of detail, she admitted to me a couple of months back that she did have 'feelings' for this guy, and she knows I'm uncomfortable with it) 

In addition to this she meets up with other guys and generally flirts/goes out of her way to be close to them? Little things like hugs, or sitting on their lap. They are nothing individually, but added together they get to me. 
So I brought it up to her and she basically told me that I shouldn't be trying to tell her who she can and can't be friends with and that I should stop trying to control her. 

The very notion that I want to tell her to tell her who are friends are is ridiculous. I just want her to try and tone it down a little bit. 

Am I being unreasonable to ask her to do this? Or is she the one being out of line?
<bot>: Girlfriend flirts with guys in a way that makes it appear she's interested. Chooses to meet them over me. Am I being unreasonable to ask her to tone it down?
