What do I do? Ignoring me?

I’ve been hanging out with this dude for months now. Things have been going really well recently. We’ve been texting every single day. He recently started a demanding job and has very limited time to do things. But he’s made time for me like me tagging along to do errands. Last night we hung out and he actually ended up falling asleep while in the car and we didn’t do anything. I understood thought because he was super tired from waking up early. This morning he texted me saying he wish he came over to my place and that he didn’t fall asleep because he wanted to have sex. I was working today so I told him if I got off early I can come. Unfortunately I didn’t and he said it was too late and that he was already in bed. Yesterday he mentioned he can come over Friday twice. So I mentioned that I guess it’s going to have to be Friday then. He didn’t really respond to that but everything else he did. I know for a fact that if he didn’t want to he’d tell me no. I’m just scared he won’t want to. He stopped replying to me but I think he might’ve just fallen asleep? I don’t think he’d mention Friday so many times if he didn’t want to? Should I just wait for him to text back? I don’t want to mess this one up
