Between a rock and a hard place?

so this week has been dramatic. my boyfriend and i got into a HUGE fight. I was texting my ex who is also my friend and my boyfriend found out and went completely insane. He pretty much broke up with me wich really really hurt because i told him this was his last chance to make it work. I told him bye and instead of begging for me to stay he just asked when he could have his stuff back? Whats up with that? It wasnt until i stopped answering that he started sayin sorry and saying that he doesnt wanna break up. We cant talk now without fighting and i think we need to take a break, just a little time apart. He doesnt agree because he thinks we wont get back together after. I really think a break would be good for our relationship. What do you think?
