I need advice

So there’s this one guy, we been talking for a Lil while and then all of a sudden he didn’t wanna talk to me no more bc he wasn’t feeling that “vibe”/ connection which wtf it was too early. I was taking shit slow but I feel like we both had huge misunderstandings, now he doesn’t even talk to me at all, nor text me like nothing and I been so upset that I just can’t take it, like idk if I should cut him off or talk it out and see wtf the problem is cuz there’s obviously sum going on if he not talking to me even tho we agreed to be cool and it’s just making me mad
