Moving on without out closure

Angelica
So me & my ex split up a few months ago. We were fighting via text and i text him a peace sign emoj(like im done with this fight) and he took that as me breaking up with him. So after not hearing from him I as aked are we really gonna breakup over a fight over text and he said yea. Maybe a week later i text him trying to work things out and he said that he sees that im trying to make things right so we could meet up and talk. When it comes time to meet up he's MIA! That night I text him when are we gonna do this and nothing, no response! I haven't heard from him since. I know im better off without out him and i dont deserve to be treated like that but i still miss the memories here and there and think about him. Do you think it's possible to move on 100% if you never got full closure??
