How long should a break last in a relationship?

Anonymous
My boyfriend wanted a break after an argument on Wednesday, the initial argument was Saturday night. Probably the worst we've ever had. He messaged me Friday about work because something came up (we work at the same place and management needed to get in contact with me and kept going to him) and we haven't talked since then. It's Sunday now. How long should a break be? Can I message him after a few days or should I wait for him? Not sure how this works.
