Overview
A friend is acting sort of oddly right now, and you could be getting somewhat suspicious of them. Try not to jump to any conclusions -- there is far too little information for you to go on. Put yourself in their place. If you were having a bad day, going through some personal stuff or trying to figure out a problem, would you want your friends assuming the worst? Support them and be patient. Find out if you can help them. If they say no, then just give them space.
