He's home.. but we aren't the best...

My SO works 2 govt jobs. He is gone ALOT. He just got back from a 6 month training. He will be back for a month before he goes on a 6 month deployment overseas. I quit my job so I could at least be with him for 1 month out of the entire year.. we are going to CA because he has to work for this 1 month as well. I have 1 month with him before he leaves again and I have felt just so shitty all day. I've been such a bitch to him. I'm just not in the best mood and nothing seems to be helping. In my mind... I'm risking a lot. We aren't married or engaged and I've already moved across the US with him twice. I'm risking so much because we just want to be together. But i'm starting to feel less of an equal... esp when he comes home from training and ALL he talks about is work and his guns ect. All I want to do is relax and love him but he's changed so much. He can't even relax. He's been cleaning the house now for 3 straight days and won't even take his boots off. It's making me uncomfortable and uneasy... I'm being a bitch. I want him to relax with me but all he says is "i don't feel like being lazy." It's starting to make me feel like I'm in the way or just this messy person who annoys him. I even offered to help clean but he says its alright. Hes being a perfectionist. To the point he tries to make the bed while i am still ASLEEP! I even saw him correcting all the clocks and picking at the walls. He wont chill..

He went out for a guys night. And I went out alone. What should I do?..
