EDIT don't know what to think

Me and my partner were spending Christmas and new years apart. We haven't seen each other since the 15th and I'm not due to see him until the 2nd. Anyways he normally messages every day we're apart. Even if it's just to say goodnight ect. But this time we've been apart he's not messaging at all. I know he's working 1am-10am but surely there's time to send a simple text. Especially when he's been on Instagram liking peoples photos and sending stupid snapchats (during the day) of him playing on the xbox ect... But no reply to messages I sent or waiting hours for a reply. He even totally ignored one of my questions and sent me a text about sex. These are the few messages he's sent

Ps I said go to sleep because he measaged me saying that he was trying to sleep so to stop messaging him... When I hadn't sent any messages... Don't know what to think. Or what to do. I do want to go up on tuesday but at the same time he's pissed me off EDIT!! We've been together 2 years. During this time he's looked after me so much no matter what's happened (I've been in hospital a lot due to a recurrent elbow injury) and he's normally very caring and living but the past week or so hes been like this.
