I can not say this enough!
LEAVE IT! LEAVE IT! LEAVE IT!!
I've been OLD for 7 years (on and off), and have learnt never be the first one to message, especially if you've had sex.
I know it's too late and you've already text him. But he's not that into you my darling. But he'll keep you on a line in case nothing better comes up.
When it's right you'll know. They're excited to see you again. As you are excited to see him.
He's not asked you any questions or arranged to meet again.
As PP mentioned this isn't playing games, this is the reality of dating in the 2020s.
I've had probably over 200 online dates, over the years. But just recently I've found someone.
It was worth the wait! No games - just fun, laughter, trust and passion.
Chalk it up for experience and when/if he texts you for a hook up in a week or so. Just decline.
It's solid destroying dating nowadays, but there is someone for you.
Don't overthink it, in fact don't think about him again. He's just not that into you.
Good luck.
