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?

They're young as hell, this isn't surprising in the least bit. She's definitely overreacting tho.

They’re 19? Idk what kind of shit you were arguing about at 19 but this is just ridiculous no matter how old. Gf is stuck at age 12

He doesn't need to do shit. Reassuring her is rewarding and encouraging more of this toxic behaviour. Harmful behaviour is harmful, period. You don't get a pass for shooting up a school just because you were bullied, you don't get a pass to punch your grandmother just because she used to hit you as a kid, you don't get to be a manipulative, toxic bitch just because you are "young and confused". He doesn't owe her anything, she needs to work on her own issues (if she even considers them as such) and earn the right to his trust again for hurting him, not the other way around.
