I suspect his is a ploy by him to get her to open her eyes.
She has some deep insecurities and needs to get over them AND learn to listen to other people when they talk. Her not listening definitely has happened before (I can't remember when) so of course he would take a drastic step to get her to listen. Even if he was being "sincere" in having them break up right now I can see it remaining a thing for just a few more chapters.
Also, when can we get back to our main couple who refuse to make any progress? I get that we need to have the girl best friend have an arc so she can accept that MC being with her best friend/ girl needing to get over her insecurities to be a better person and friend. I also get that we have these 2 side characters who are friends to the main characters who apparently have a lot more layers than normal side characters, but I signed up for a fluffy romance and I have not seen that for awhile.
