new relationship question?

Sadly for you Barney, you went along to meet him feeling and looking for something special, however, he wasn't so thoughtful in his intentions despite all the speel he'd given you through text! There's a lot of that happening, "again sadly" for people such as yourself looking for romance once you're in contact with someone. All the above presented by you was honest and dear to your heart but this loser wasn't. On his behalf as a fellow man, I apologize unreservedly and hope you'll find joy and happiness again real soon.  

The issue is, you go on one date and call it a "new relationship".  That's a sign of being clingy.

Don't text a guy after a date. If he had a good time, he will let you know. And he didn't even take you out on a date -- he expected you to hang out with him? What? First he talks you half to death for two weeks, then he just hangs out with you and doesn't even take you anywhere.

Sounds like a totalAss to me, unless you never had any intention of more than hanging out, making out and/or sex.

move on, but first ask wth he is doing

You may not be overthinking, but your concern is understandable. You can move on, but that doesn't mean, if he gets in touch with something you'd like, you can't have more interaction with him. You did the right thing and now, if there's going to be any next move, it's up to him. You can wait for him and risk being disappointed or you can go on with your life and, if he gets in touch, take it from there. That's probably your best option.

this date was just a hook up to him. maybe you should have refrained from fooling around

i personally wouldn't do so much with someone i've only texted for 2 weeks and just met once

My gut, based on your gut (weird vibes), is its time to move on. Don't take it personally, we can't float everyone's boat, even those we wish we could.
That being said, I'm just some idiot hanging out on YA answering strangers' questions so....what do I know lol.

He might have just been after casual sex and thus lost interests after it didn't happen. But text him one last time in a few days see if he response, if he doesn't then move on.

Maybe he doesn't like clingy people. Give him some time to wake up and have coffee. Be patient.
