silence this loud

So we were talking last night after my orientation for a while and I asked/mentioned about what we should do Friday and he wasn't sure and stuff and I said to let me know, he said he will, and I said good :) and he said yes(: so that's good right? but then like 2 texts later he stopped texting me back... and I get it was kinda the end of a conversation but still... And I decided I'd just wait for him to text me back... but he hasn't yet. And it sucks because I know he's texting plenty of other people, just not me. I'm not sure what to think of it. And I know that really trying to pull him in will only push him away. So I don't know what to do. How long do I wait before I text him? I hate this. I thought we were past weird days like this. I hate feeling like I'm back to where I was 2 months ago. Maybe it's nothing but idk. I wish he would text me. He works this afternoon I'm pretty sure but he's usually done around 9 so I guess we will see then.... But what if it gets to be like 10:30 and he still hasn't texted me? Should I say something? Like I miss you or a goodnight text or what? This is all too complicated. I hate it.
