Is he ignoring me or??

So I have been talking to a guy that I met on tinder which of course is a hook up type of app. We seemed to have a lot in common and were taking for a week. We decided we would meet up this weekend but he has yet to respond to my last text.Am I over thinking it or did he just ghost me? He added me on fb two days ago though so idk. We are both studious and working full time so maybe he is just busy?? Should I not put much thought into this??
