<human>: Can you succinctly summarize the text in 1-3 sentences?

So I've been dating this guy casually for about 6 weeks now, in that I don't want a relationship but we still wanted to be fwb. I encouraged him to keep dating since he does want something serious. We've become pretty close and I thought we really enjoyed each other's company. 

He came over Friday night. It wasn't super eventful. We just had sex, talked, fell asleep. He left at about 1 am (I had told him I was super sleepy before so this leaving early was expected) and I told him to text me when he got home and he said he'd text me the next day about the plans we'd made to hang out. So Saturday night was approaching and I never heard from him. Around 9:30 pm I texted him what's up. Part of me is worried because he didn't text me when he got home. Like, is he okay? And then his phone had fallen off the bed while we were having sex so I'm like, did his phone mess up? I know his last name and could contact him through facebook but I feel like if he's truly ghosting, that would be creepy of me. If something crazy did happen with his phone, I think he'd be appreciative that I found him on facebook.

I'm the only person he knows in this town (unless he did start dating others and moved on from me) so if something is wrong I feel like I should do something! Idk how accurate tinder location is but I could see that he changed from 3 miles away to 5 miles at one point. I don't know if this is a glitch or what. I hate feeling crazy. I am just worried. What is appropriate for me to do in this situation?
<bot>: guy stopped responding unexpectedly, he could be ghosting but I'm also just worried. What's appropriate for me to do in this situation?
