Breaking my engagement

So December 2018 I caught my fiancé cheating on me with a coworker. She was an acquaintance of mine for a few years before the job which made it worse. I was working on my MBA at the time so I didn't have a lot of time to monitor their relationship. I asked what was going on and he lied several times. He broke up with her December 2019. I wanted to try to make the relationship work and gave it a shot for a year, but he has a lot of issues including being a rageaholic and I can't overlook them anymore. I'm devastated that the life I planned is just gone. I saw a whole future with him and realize now that it was all smoke. I'm just numb towards it all now. We're in transition. He's going to help me move out, which is kind of him, but he wants to talk everything over almost everyday now, and I don't have anything else to say. He constantly says "I'm just processing it all." And I almost want to get angry. Like "what about what you put me through?! I still haven't processed that." I know that's not productive and I don't want to attack him. I just feel so lost.
