Has anyone ever had their bf ask for "space" and not ended up broken up?

My bf of 2 months, who has also been my best male friend for a year and a half, got upset with me the other night. I did not follow through with some plans we made for me to stop by and visit him. I was in touch with him via text and he knew I was with friends, but when I offered to come by later than we planned, he said he was going to go to bed. I felt very bad about it and apologized for making him feel unimportant. He accepted my apology but then said he needed some "space today". Well, it appears that the space is going on for longer than that. Now I am wondering if he really wants to break up but doesn't want to say it. I am trying not to ask too many questions or put any pressure on him, but I feel in limbo. I told him I wanted to make things as easy as possible for him, implying that I accept if this is a breakup, but he said he is just overwhelmed and confused and needs some time, that this is not the "end of all". I will see him at work in a few days. What to do?
