(30M) Boyfriend left my (28F) house and is expecting me to reach out?

Yesterday my boyfriend was at his friends out and he drank a little bit but he wasn't drunk. He came over to mine and was just giving weird energy and wanted to sleep since he had work all day. My friend was speaking to me on whatsapp and for some odd reason I'm not sure if it was the alchohol but he thought it was a man and wanted me to call her so he could listen to her voice to confirm if it was a girl and it was obviously. This rubbed me the wrong way. He said he was going to sleep and I said to him "go home and sleep". He looked at me for 2 minutes grabbed his stuff and left and hasn't texted me since last night. I think he's expecting me to text him?
I want to reach out but **** that I?m not doing it. Yeah sure I said leave but why leave without no communication ?
Why the **** do men do this?
TL;DR - silent treatment after an argument. Why do they expect you to reach out first?
