Maybe help idk

I have been with my boy for 9 months, we have recently been going through a rough patch but, have decided to work on things. Until something happened friday that has confused me on what to do.

I cant handle it when people yell at me, he knows this and knows that when people yell at me it messes me up. But on friday he yelled at me, he knew it was wrong and keep apologizing. I keep acting like everything's okay but I cant get over the fact that he did that. Idk what to do...
