Is there any chance for me to get him back after acting crazy about the breakup?

Hey my partner and I were together almost a year, however our relationship grew in strength very quickly therefore it was more like we'd been together for years. We were living together and very happy apart from the usual small arguments... He told me he had never been a very romantic person but all through our relationship he tried so hard to do cute little things all the time... He told me I was his soul mate and that he wanted me forever... We made so many plans and had our lives all figured out... And then one day in the middle of an argument he told me he had cheated on me and therefore wouldn't care if I left... I was devastated and left, but he didn't want me back and didn't want me to give him a chance... I later found out that he hadn't cheated at all and just thought saying he did would make me leave without a fight... It's almost been a month since the breakup now... I have been acting crazy, calling him, begging for him to give us a chance and telling him how I feel about him... Have I ruined any chance of getting back together seeing as the breakup was so sudden and unexpected? If I had have just ignored him would I be back in his arms right now?
