Will my ex boyfriend ever forgive me?

my ex boyfriend broke up with me a month ago we have been on and off since this last time we were off he said he needed 3 weeks before he would talk to me. I didn't understand why so I kept texting him blowing up his phone now he is mad and is saying mean things like he is over and f*** you and he never wants to talk to me again. I think he is just saying that because he is mad from me blowing up his phone do you think if he still has feelings that he will come back if I stop contacting him and giving space and or do you think he won't come back and what he is saying is true
