I'm getting scared of my fiancee

I've been with him for almost 7 years we are supposed to get married this November the 23rd but unfortunately I am struggling to get a job and my father past away about 5 years ago so he can't pay for the wedding my fiance has a job and so he is paying for the wedding we are keeping it small and at our house but it's still quite a lot of money and now whenever he feels he cropped up his emotions for too long he takes it out on me he insults me for not having a job, and that breaks my heart. He lifted his hand for me today which he has never done before that hurt me so much. I love him but he seems to be struggling with anger issues and I'm getting afraid and getting tired of being insulted every time we get in a fight. Any advice to what I can do I don't want to leave him but I also don't want to be insulted anymore
