Sounds like he's being nosy. Hard to say whether he's showing signs of being controlling. Some men get anxious, He may be worried that you have someone else occupying your time while he's gone. With him being away a lot I could see how anyone male or female would get a little worried about something like that.
If it becomes a pattern then you might have to confront him about it and perhaps even reevaluate you're relationship. If he needs to now what you're doing and when every second of the day then I'd say there's a clear problem, but he may have been worried that there was another reason why you were at home and not at work. If you do fee like you need to confront him, make sure you say in a way that expresses how you feel without coming off as a personal attack.. ex. I feel (place you feeling) when you (what he's doing), I need you to (what needs to change)
Hope this helps :)
