<human>: Can you condense the text into a few key points?

I find myself [M24] and my girlfriend [F23] of three years still debating insecurity issues.  Today we were talking on the phone about the possibility of me meeting up with some friends that I haven't seen in a few months at a bar.  I rarely go out, and am a bit of a hermit.  I like my own space and see my friends infrequently; though when I do decide to venture out I find myself having a good time.  

When I brought the possibility of me going out sometime soon, she brought up the fact that all my (male) friends who would be attending are single.  She voiced her opinion that she did not want me talking to other girls at the bar.

I then stated, that I will not engage any women intentionally, but I may have to talk to some strangers if my friends attempt to hook up with someone outside the group.  Then she stated, that even if my friends were to start talking to women, she expected me to hang back by myself/leave the bar, essentially bailing on my friends for the night.

I told her that I'd hang back for a bit but if my group of friends is talking to a group of people then I'll probably at some point join them.  I would introduce myself and in the beginning state I have a girlfriend to prevent any future misunderstandings.  I'd only let them be, if I felt they had a chance of going home with a woman/if they were all talking one on one to their potential "dates" for the night.  Still not good enough.  I reached the end of my rope, and our conversation abruptly ended.

I feel like I'm treated like a child, that she doesn't trust me at all.  I told her I loved her, and I don't want to talk to other people whatsoever, but it didn't change her opinion in the least.  It seems there's nothing I can do to please her other than shunning my social life altogether.  Is my girlfriends reaction common to other relationships?  Or is she over the top?

My friends have big mouths, and if I say anything to them I'm afraid it'll get back to her.
<bot>: My girlfriend doesn't want me speaking to anyone of the opposite sex when I go out to bars. Is her reaction over the top?
