I need some help?

So on Saturday my boyfriend tells me that he needs some space not single space. that we are still together but that he just needs some space. what does that actually mean. and i haven’t talked to him since Saturday morning. should i prepare for a brake up? or is it that he just really need some space from me. mind you he is a truck driver so we already hav space we don’t see each other that often.
I need some help?
