Is he a red flag?

Guys there is a man whom I met on an anonymous app. We had been quite good to each other and from there shared our socials. A few days back he said let's date like an actual relationship however I said I am not ready so let it be casual till we meet (we live in different cities). So basically we chat on that very app and on snapchat too. Sometimes he wanted to talk on call but I didn't want to. Two days back I uninstalled the app and said I am going off for some days. Do you wanna exchange numbers so we can contact on whtsapp but he said he doesn't use that app. it's just for formal stuffs. I somehow believed. I didn't contact him then and today he was (in snap) like why are you still off I said I told you before about that and also asked for your number but you denied. So he said ok let's talk here. I said i dont want to and stay happy with all your chicks.. He replied he doesn't have any chicks and if i dont wanna talk its ok. so should i avoid him or say something? if yes then wht?
