He left me on read 😞😞😞

I’ve been talking to this guy for about a month and a half. We’ve been out a couple of times and we talk every day. Yes we have been intimate. Things seemed to be going Pretty good. He does work the overnight shift and sleeps in the daytime but we somehow have made it work even though my schedule is the complete opposite and I also have a two-year-old. He text me at five in the morning yesterday letting me know he made it home. I responded when I seen the message. Most likely he was sleepy because I tend to respond a little late because I’m sleeping at that time. He usually text me when he gets up, never got a message from him waited until almost 7 PM to text him to see if he was OK. Never got a response fast forward this morning at 6:30 I see he did open the message but he never responded and now it’s after four and I still have not heard from him. Does it look like he’s cut me off? I’m so confused and don’t understand because everything seem to be fine. I thought maybe he just wanted to take a day to himself but it’s been over 24 hours and this is definitely not him. I’m actually pretty upset about this. 🥺🥺🥺
