What was the fight over in the first place? that would help a lot.
If it was something petty and silly....then I think he is trying to let you go as easy as possible. Trying to beat around the bush about it, not wanting to sound harsh or hurt your feelings.
if the fight was over something major...then he may honestly may just need the time and space. In which case, you must give it to him. I'm the same way. When I'm angry with my fiance, I need the time to think things thru. I have a habit of jumping the gun and making the fight 10x worse when I don't have time to think and process the whole incident.
What ever the case may be......you need to relax. You can't change what has happened. It's so much easier said then done, this I know.
Don't jump to any conclusions just yet.
