What should I do if my boyfriend hasn’t talked to me since Sunday, due an argument that we had? Is that a sign it’s over?

We’ve been together for 2 years, and almost all the time we got into arguments, I used to be the one breaking the ice. This time, it was completely his fault and apart from a “hope you’re okay” text from him, which I replied, it’s been radio silence since Sunday.
