AITA for telling a friend why she’s no longer invited to fancy corporate events?

I (30F) regularly get invited to corporate mixers and parties for my job. I can often bring a plus one and since I’m single I’ve asked a friend (Also 30F) to go with me a few times. The friend is a bit socially awkward and has a way of saying the wrong thing. At our last event a few weeks ago, she did a few things that embarrassed me including going on and on about how great a competitor is to the host (when I brought it up privately, she said she thought the two companies were “more or less the same thing”) and taking advantage of the open bar to the point where I had to help get her home. This was not the first incident of her acting this way but was the worst. As a result, I have stopped inviting her to anything connected to my job and instead only grab drinks or dinner from time to time.

She has learned that I still go to these things for work through a common friend and asked if she could go to another one since money has been tight and she could use a free night out. I said it’s not looking good and when she pushed me as to why, I told her the truth: that her behaviour at the last event was disruptive. She freaked out and said that I was more interested in “image” and “the corporate ladder” than friendship. AITA?

MORE INFO: She also said it wasn’t fair of me to judge her drinking when she’s only 4’11 and “can’t drink as much as you can without getting drunk” (I am 5’10 but still never have more than two glasses).
