Any advice please?

My boyfriend and I stopped talking after an argument that he caused on Saturday at 12pm. Till today he hasn’t reached out and I haven’t done so either because I can be labeled as the “fixer” in our relationship. Always willing to reach out to fix our problems even when some of those problems are started by him. He’s not the type to admit to his mistakes and understand what he did wrong or why I’m mad. He always blames me in his head and idk what to do. I’ve always been the one to talk to him about our problems in order to fix it never him. Before there’s been days where we argue and then he never reaches out. It’s always me that does it and he can let days go by without reaching out. Idk what to do, we haven’t talked since Saturday and I want to reach out I do, I want to fix this but I haven’t reached out because I wanted to stand up for myself and have him reach out since I always do it to atleast show that he cares. But he hasn’t done it and idk what to do. ☹️ should I just reach out ?
