double texting when horny?

Hey all. new here. SO I am having a bit of a problem. 2 weeks so I slept with a guy, just casual. I am really horny & he was the first person I slept with after 6 months of abstaining. The sex was really good. & I have a tinder account, but I honestly want to sleep with him again. SO here is my not so much of an issue.

last week Tuesday he texted me around 12a. I was asleep and didn't see it till I woke up. I got back to him that same night I opened the message. I texted him & said "what are you doing tonight?" He did not respond but left the message on read.

Usually when a guy is not interested in me I take it for what it is and fall back. It's just been a while & it felt pretty intermate. Ive been talking to other guys but I want to sleep with this one. I'm not sure why I feel sad about it. I wouldn't exactly consider it to be me being ignored, more so him being that interested. I'm a little blue because its like, I'm okay with casual arrangements but you can't just **** someone so good then disappear.

I do know that I need to take it for what it is. I shouldn't be wanting someone who doesn't want me. I'm just really horny & he lives like 5 minutes away. Should I send a late night text or let him go?
