There could be a million reasons, but it probably feels A LOT longer because you're waiting for the call. Try to forget about it, you have to act nonchalant when it comes to things like that, or it makes you look obsessive. Give it a few days, if he doesn't call, casually bring it up in your next chat online.

It's quite simple, he's being alpha as displayed by your post, the fact that he hasnt called makes you want him even more. He probably likes you alot but does not want to come off as needy, so iniate the convo

yea don't worry, he opened up to you a little too much so now he's trying to retract.

as a guy i love when girls call me. not all guys are manly as you think. i love when a girl text first, kisses first, and does everything first.. but then i also like to be romantic and switch it up

He's probably scared to. You are talking to guys on the internet, after all.
