After a little fight btwn us he decided to leave me?

I was upset about the fact that he didn't answer to my phone call at 10pm ! He called me 20 mins before and i said that im calling my mom.
The dayr after he send me a message at 2pm telling me he was sleeping that s why he didn't answer.
He never sleeep at 10pm N E V E R ! Than i yelled because i knew he was not sleeping than he broke up with me.
Is he acting like a child?
