Hookup Hasn’t Been Responding to My Texts

I met this guy on tinder a bout 1 month ago. This first time we hooked up was at his house and it was the best sex of my life so far. He texted me later that night that I was the best sex he’s ever had too. We both agreed to be casual hookups. We text about things unrelated to sex every now and again so we aren’t just having sex, he’ll ask about my day sometimes and vice versa. I thought things were going well until a week or two again I texted him asking if he wanted to meet up later in the day and he didn’t respond. He hasn’t responded to my texts since! I’m not into him and I’m also not crazy. I’m just really confused why he’s “ghosted” me because he seemed to be a little more into me than I was into him and he even said things like “in a couple months we should try anal” and stuff like that so I just find it to be so weird that he’s ignoring me all of a sudden. I’m not sure what to do. He’s a really busy guy but normally he’ll just text me and tell me he’s busy but I’m not getting a response at all. Does that mean we’re over?
