<human>: I've been seeing a girl for a week and a half and we've gone on 2 dates so far.  The first week she was texting me non-stop and on Friday I spent the night at her place and we had sex.  She told me she liked me a lot and acted like she did, but she did comment that I was very closed off unless we were drinking together.

I texted her last night to see how she was doing and eventually I was going to see if she wanted to hang out on Wednesday, but I didn't get a response.  I feel like texting her again today would give the impression that I'm needy.  Am I just overthinking things, or should I wait another day or two to try and get ahold of her?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Girl I've been seeing for a short time suddenly didn't return a text.  Should I wait before trying again?
