So, my girl has a friend that recently broke off an engagement, so she naturally wanted to go party.  Totally understandable that my girl would support her friend.
They go out together, and get a bit too drunk.  My girl is in a public bathroom throwing up, the other girl went with her to the bathroom, but then left her alone shortly after to leave with a married man.
I came to pick up my girl from that random bathroom she was abandoned in by the friend who took her out.
I sent the friend a message saying “you left ****** alone and sick? What the fuck?”.  To no reply.
Then several nights later, I went out to meet my girl and her friends at a bar.  I asked the girl why she left ***** there alone.  No personal attacks, no ad hominem, just asked why she did that, albeit in a confrontational tone.
Without responding to the question, the girl said “I don’t need to answer to you!” “*****’s a piece of shit, don’t ever ask me to hang out when he’s around, you deserve better”, then she stormed out of the bar.
Am I the asshole for asking her why she did a thing that she did?
