IN NEED OF EX BOYFRIEND ADVICE ASAP !!?

okay me and my boyfriend broke up and instantly was crying and begging for him back, and like texing and calling him constantly.... he thinks the only way to "get things through to me" is to be mean, so he yelled at me to leave him alone. I feel as if i completely screwed up everything because all the "how to get your boyfriends back" say do the opposite of what I did. I don't have a clue what to do at this point.
