My friends and I usually hold our birthday parties at a bar we all enjoy. At the time of this story, [Friend #1] has recently moved in with his girlfriend as his birthday approached, and so had warned us that we might need to pick a different venue from usual.
This SHOULD have been his (and our) first red flag, but we, the dumba**es, just assumed the different location meant the bar was now out of his way enough to make travel questionable. When he confirmed the usual spot would be fine, we let our worries fade away.
His birthday arrives, and we eat, drink, and be merry. Halfway through the festivities, [Girlfriend] shows up.
Girlfriend: “What the f*** are you still doing here?”
Friend #2: “We’re having a party? That’s kind of what birthdays are for.”
Girlfriend: “Go f*** yourself.” *To [Friend #1].* “Why the h*** are you drinking?”
Friend #1: “Because the drinks taste good.”
Girlfriend: “Are you done?”
Friend #1: “Done what?”
Girlfriend: “Being drunk.”
Friend #3: “That’s… not how alcohol works.”
Girlfriend: “F*** you, too.” *Grabbing [Friend #1]’s arm.* “We’re leaving.”
Friend #1: *Wrenching his arm free.* “No, YOU’RE leaving. I am going to enjoy my birthday party as I TOLD you I was going to LAST WEEK.”
[Girlfriend] stormed out of the bar and waited ominously by the curb until the bouncer drove her off. [Friend #1] moved out of her place the very next day and crashed with me while he was looking for a new home.
Years later, he refers to her barging in on his birthday party as “the best birthday gift she could’ve given me” – a giant warning sign that she was going to try and force her preferences on him as long as they were dating, allowing him to get out of the relationship ASAP.
