What is up with my husband?

For a long time now we it seems like we have been doing really good. It seems like we could not be anymore in love, but tonight when we were going to bed he turns on this war movie. I asked him to turn it off because I have to get up for work early in the morning, and he throws the remote at me, and says "turn the ******* tv off!" I was like whoa! He must be really mad, I figured it was so important to him, I told him that he could watch it, and I'll just get over it. I tried turning it to the chapter we left off on last night, and he said really pissy to me "why do I give a ****". I told him to stop acting like he is in such a bad mood because Im trying to do something nice for him by sacerficing a little of my sleep. So then he pushes me. Im really confused. He has NEVER acted like this before. What do you think could be the matter?
