<human>: A few days ago my girlfriend mentioned taking a trip to go to a concert together and I said it'd be fun. She just mentioned that she had invited her friend and her friend's boyfriend to go with us in casual conversation today. I had assumed it was just us two going...and asked her why she didn't talk to me about it first, before planning a trip with another couple. 

She got very defensive and said that she shouldn't have to "ask for permission" every time she makes a decision, and that she would tell them that they can't come with us anymore. She said that she'd understand if was a date or something like going to dinner...but that in this circumstance she was trying to get a group together and didn't feel like she needed to talk to me before inviting people. 

I told her not to cancel the invitation, because I don't mind them coming...but that my point was that she should have talked to me first. She continued arguing her position, saying sarcastic things like "wow, I didn't realize it was a date weekend," and "you're really mean to me." 

I told her I wouldn't put up with the rude comments and that voicing my concerns is in no way being "mean." So I said I was going to bed and would talk a different time. She told me not to break anything in the apartment or wake the neighbors. I said "excuse me?" She told me that I sounded angry and that she was scared that I'd get mad and break something or yell and wake the neighbors...yeah....I didn't know what to say so I just hung up. I felt like that was a ridiculous thing to say and that it was a passive aggressive attempt at trying to push my buttons. (She's on vacation with her family). 

Reddit, give it to me straight on this one.
