I am going crazy!

My husband received a message about 10 minutes ago. I had just happened to get up to turn off the lights and tv when I laid back down and hear the phone. He was knocked out... Or so I thought so... I slowly started to get up again bc I wanted to get his phone.. Why is he receiving messages at 3am?? Makes no sense but then again he works for himself so he has a lot of people contacting him through out different times or could be a Facebook notification. .. IDK... So I'm trying not to make any noise and then I hear "Cindy...where are you going" 
DAMN!! he woke up!! So I had to play it off and said I'm going to the bathroom. He asked if I wanted his phone as a flash light...I said I didn't want it... He never asks me where I'm going so it was kind of weird but then again we fell asleep mad at each other last night.  So then I'm thinking... Hmm... If he's been texting someone he wouldn't offer it AT ALL. But I still don't know who texted him....I'm going crazy...
