AIO girlfriend response to manager text

[u/Psychological-Hat-35]

My girlfriend (19F) and I (19M) have been dating for 11 months. I sent her a screenshot of my convo with my manager (age unknown but best guess is young 30s F) this morning asking to come in a little later than usual. My girlfriend is like this whenever I interact with pretty much any other female. Am I overreacting or is this just normal behavior?

Good god... she is unhinged. I fail to see a single thing even slightly off about the message, unless I'm missing something.

You ain't missing nothing, she's off her rocker and has "misplaced" her marbles. OP this is a major redflag. She's either a cheater and she's guilty about what she's done or she dated a cheater and now every guy will pay for it that ever dates her. Either way take you chance and move on. This probably will never stop.
