<human>: So I'm a little confused on what's happening and could use some outside, unbiased opinions. 

Background: For the past few weeks, I've been casually dating this guy. We met on Tinder and have been seeing each other about once or twice week since we met (probably about 6-7 times so far). Each time we hang out its either dinner, drinks, and then usually sex. We generally exchange a few texts during the days, but nothing too lengthy. 

Last night, we had plans to hang out. I texted him about an hour before asking if he was still into the idea and he said absolutely and he'd love to hang out. We started texting about where we were meeting up and what we were doing and suddenly the texts just stop with no plan finalized. The time we were supposed to meet comes around and still nothing. I send him a quick text saying to add me on Facebook (neither of us really use it so we hadn't done it yet) and message me because my cell phone signal was really bad at my apartment. Still nothing. Finally 45 minutes after we were supposed to hang out, I give him a call and it goes straight to voicemail. 

Obviously I'm bummed. I'm fully aware our "relationship" isn't anything more than a causal hookup (and I am 100% ok with that) but it still sucks to get stood up. I'm doing my best to give him the benefit of the doubt (phone got broken, major emergency, idk) but I just noticed that his Tinder profile says he was active 12 hours ago (long after our missed date), so now I'm not sure what to think.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Made plans with a casual hookup who stopped replying mid conversation, phone went straight to voicemail, Tinder profile shows up active after our date was supposed to occur.
