aio for this guy i’ve been seeing withholding something he “found out” about me

we’ve been talking for about a month, he didn’t reach out to me all day on Friday then randomly hit me with an ominous text saying “do you think i’m that dumb” and i questioned and questioned and got nothing all night. Then I asked this morning if he even wanted to talk to me anymore because I have been basically ignored for 2 days now. And this is what I got. it’s 3am now and I still haven’t heard from him. And he is also friends with his ex. Who I am pretty sure he was hanging out with tonight. Chat am i cooked
