Did I get blown off?

I (22F) started a new job exactly a week ago and there was a boy (25M) working there that I thought was sorta cute. We didn’t talk much until our shift together on Sunday and I felt like we were vibing pretty well and he started asking me questions about my life so I thought maybe he was sorta interested? Anyway I didn’t wanna get ahead of myself but I’m really bad at picking up on signals so sometimes I underplay my attraction to people to protect myself .. which maybe happened here idk. After work that day a couple guys plus this cute guy invited me out to get drinks and it was really fun and they introduced me to their other friends. After drinks they came to my place for a little bit and the cute boy decided to drive over in my car with me.

Around 4 am I started getting cold and he offered me his hoodie. Again .. don’t wanna read into it too much. When it was really late everyone decided to leave my place but this boy asked if I didn’t mind him staying over since he drove there with me so I said sure and we stayed up until 5am talking and then I went to bed and he slept on my couch. I slept in his hoodie which he lent me. I was also glad he didn’t really make a move on me while we were alone at my place bc we still haven’t known each other long but anyway I drove him home the next morning and he asked me for my phone number when I pulled up to his driveway. By that night (Monday) he texted me and it seemed pretty flirty. Then he asked when I’m free next so I told him Wednesday (today). He responded and said he doesnt work Wednesday either and we could go hike or get drinks or something and I said sure that sounds good but we never officially picked a time or a specific thing to do. I just figured when the day came then we’d figured it out … well today came and absolutely nothing happened.

I texted him and said “lmk if you still wanna do something” and then immediately after I said “also I started watching the show you recommended me” and when he texted me back he ignored the hanging out part and only asked how I liked the show … I’m confused. He’s the one who initiated a number exchange and texting me and asking to hang out and ?? Maybe I just didn’t reciprocate interest as much as I should have? I have to work with him for the next four days in a row so I don’t really understand what happened here. To me he seemed pretty interested and then it all seemed to die in one day ?? Am I missing something? Why would he have lost interest so quickly
