Will he ever come back to me?

so me and this guy have been together for a little over a month now and we really do have a uber strong connection but i guess it kinda broke today. we had our first fight and i guess it was more of me yelling at him because he broke up with me for a very idiotic reason. he dumped me because he didnt want to hurt me anymore and because hes too insecure with himself and doesnt want that to hurt me. the thing is hes never hurt me before like any of my other boyfriends did and i really do love him. i just dont know what to do because i can tell that he didnt want to do it because he was crying too. i told him that he needed to die and that i hated his guts because he dumped me! i was just really pissed off so i guess you could say i said some things i didnt mean at all. the truth is i love him with all my heart and hes my world. i dont know what to be without him. even though he doesnt think that hes perfect he is to me. i just want him back so how do i do that?? cause i really really like this guy not to mention he bought me a promise ring (i think) and ive never ever got it yet. i just need help :/ what do i say to him to get him back cause i know he wants the same thing... oh, and i also would like some very details answers because that would help a ton!!! thanks:)
