Is he trying to teach me a lesson or is he serious?

I texted something that made my boyfriend mad and he texted me back saying he was done with us. I tried to call him the entire next day and he wouldn't answer my calls. I texted him asking if he still loved me. I said if he didn't love me anymore that I would leave him alone and never bother him again. He didn't reply back. Is he ignoring me to teach me not to say silly things to make him mad or is he really done? I thought if he didn't care for me anymore and really wanted me to leave him alone he would've told me he didn't love me.
