My ex boyfriend only texts me at night?

Four days ago, I decided to end things with my bf of 13 months. I dk, all of a sudden he stopped appreciating my time with him. He would fall asleep on me during his free time. Or hed get what he wanted and then fall asleep. We don't communicate anymore. And when I do, hes getting distracted or he falls asleep on me lol...in person.

The last time I spoke to him I told him to stop telling me that he loves me and start showing me.

I haven't called, texted, nada.

He's called me once out of the four days of no contact. I didn't answer though. And he's texted me twice during the day but the other apology texts were sent from 1am-3am. Like, I know he has crazy work hours but why can't he find a decent time to send me texts. And what's does this all mean? I want more than a text or call. Or is that expecting too much?
