Input: So my group of friends (6 guys ~22-23y/o) has this 2 y/o tradition where we go to Boston for St. Patrick’s day and stay for the weekend, this year being the third time. We always go with the 6 of us and anyone’s gf. My best friend has been dating this one girl for about 8 months now and of course wanted to bring her along. Myself and one other in the group planned to bring their gf as well. So four weeks prior to st.Patrick’s day we’ve finalized the guest list (9 people) and reserved everything (bar crawl tickets, restaurant reservations, hotel rooms, etc. Now, for my best friends gf of 8 months this would be her first time there and, might I add, she was not very accepting of what we had planned - suggested different things/said she didn’t want to do the things our friend group typically does. 

Now a few days ago less than one week before we take the trip I get a text from my friend saying the gf has invited one of her friends to come along and the friend accepted and is planning around coming. She also expects that we accommodate her friend and adjust accordingly. Now I know the friend and she’s very nice and I have nothing against her - matter of fact we’ve gotten along pretty well the times we have interacted - but it’s much too late to change plans. Long story short, for her to be able to come we’d have to get another hotel room (we are all splitting the rooms equally so this would make the cost for everyone higher by about 100$ since all the rooms left at this point are very very expensive), get tickets for a different bar crawl than the one we already had cause they were all sold out by now, change the dinner reservations (not a big deal) and drive another car there (4 hour drive there and back). 

Of course I wasn’t gonna stand for that and flat out said she can’t come and to tell her she isn’t going and that his gf doesn’t get to invite people to go on our trip cause it’s our trip and she’s a guest on it. I also said she can’t make this trip HER trip instead of our friend groups trip as much as she’d like to. I’ll admit I came off a bit rude when I said this but AITA for saying her friend can’t come? 

telling my friend that his gf couldn't bring her friend on our trip
