So there's this girl that I hooked up with a couple times and talked to in may/june. We haven't talked much lately, especially since the summer started. She called me at 8:30ish, but I was at dinner with a friend so I didn't pick up. When it went to voicemail, I texted her saying "I can't talk right now...what's up?". She hasn't responded yet. Should I text/call her again or just forget about it and not say anything?
