Everyone here is acting like she’s a complete psycho who‘s gonna snap and kill him any second now, but honestly, this is barely outside of how I would expect stupid teenagers to act. The dude literally did not text her back for an entire week and offered no explanation as to why.
In high school, I knew guys that got screamed at dumped for not texting their girlfriends back within an hour. They’re teens. They’re overly emotional and react in stupidly Insane ways to almost everything, especially romance.
