i want him back, help...

so me and my boyfriend, (now ex) were together for two years. he dumped me last monday, so it’s been a week since we broke up... i really really want him back... he said that it was a possibility, but he’d like to move on and he wants to be friends. (basically saying if it happens, it happens) so i am on day two of the 30 day no communication process, but i’m scared he’s gonna move on.. also, i watched a lot of videos what to say after the process of no communication.... we broke up because we were always arguing and he wouldn’t text me back... (i caused all the arguments) and he said he wasnt happy. though out this 30 no talking process, i am working on myself. i don’t know what to do afterwards.... also we talked otp a few nights ago and i’ve already f’ed up by crying and talking about how sorry i am.. i’m scared... am i stupid? i would like to be with him and make something better. please only positive suggestions he’s the love of my life.
