So this is me and my gf 1 year anniversary, I just want to put it out there that she knows that I am introverted and that I also don't really click with her friends. They are more like party girls that are boy crazy... just for more context I am 25 year old male and she is 26. I've expressed that I don't really like one of her friends because she disrespected our relationship by sending my gf videos of men working out for no reason (according to my gf)and other stupid childish stuff. We were planning to go to another city that's 2 hours away from our home town and I would be working remotely while she would be driving. My girlfriend knows I don't like working with people around me aswell. fast forward my gf tells me today that her friend asked her if she could come get a ride from us with one other friend & she also added "let me know because we never know with your bf" Already just hearing that " we never know with your bf" gave me a distate. My gf told me she told her friend she will ask me and let me know. I know my girlfriend did the right thing by telling her that she will let me know. I don't mean to be unreasonable but in my head I can't help but think, why would my gf tell her that we are going away for our anniversary? I am a big believer in keeping things private specially when it's positive things because people like to leech off of other, I also understand that this is not a big deal but the issue is that my gf really tells too much of our private lives for example. I got promoted at work and I got a big salary increase making about 87k per year and she told her friend and family. I truly don't appreciate these things because people than view you as a cash cow or leech off... anyways I canceled our anniversary trip because I know that my gf knows that I don't like this girl and that I know that she knows that I would've already said no & she could've easily told her " sorry this is me and my bfs special day " honestly this completely killed my vibe because I was tryna play my music " work and just enjoy each other presence" & to be fair her argument was that it's just a ride and that she wouldn't stay with us but I know how it gets with my gf, she'll end up seeing her friend because she'll be in the same city as us and all that. Was I wrong for canceling on her ? I told her she could still drop off her friend and that we could reschedule our anniversary on another day.

Edit: Thank you for the responses, I don't talk to anyone about my relationship issues so I feel out of touched with what's wrong and what's good, my gf is giving me the cold shoulder because of this but I understand why she would be a little upset but the thing is, is that it really saddens me that she doesn't try to understand that I really wanted this to be about us and her response to this is really not helping. These little things really play with my mind when it comes seeing a future with her. I have issues thinking too much and looking into behavioural patterns. This really scared me because it should've never been this serious to the point that I go on Reddit to understand if I am in the wrong... additionally it's not often that you hear guys taking a 1 year anniversary more serious than the gf... Maybe I am just renting at this point but this really unmotivated to do something nice for our anniversary or even taking it seriously now. It kinda shows me where her head is at when it comes to her priorities. Maybe this is also a good thing to know when we stand.
