Talked immediately after dumping me??

So my ex broke up with me on Saturday. NOT EVEN AN HOUR after, tries to video chat through Messenger(which I miss bc driving and also GETTING DUMPED OUT OF NOWHERE), and starts talking to me like everything’s fine. Like friends would. But ever since then no contact... I’m confused... I’ve heard guys cut off contact after a breakup bc that’s how they heal or whatever, but why would he try and talk to me right after? Has this happened to anyone else? Lmao
