Is all this pain worth being a military wife???

My husband of almost 3 years deploys in a few days and here lately we have been fighting about the stupidest stuff!!! I dont know if its the deployment that is getting to him, i kind of don't think it would be to the fact that this is his 2 deployment!! But i don't know, when we fight or argue he just get so mad so easly and throws things sometimes breaks stuff puts holes in our walls with his fist!!! Im scared that he is going to deploy and we are going to leave on bad terms, he is going to be gone a year and the last thing i want us to do right now is fight, but even if i say the littlest thing he blows up!! I don't know what to do!!! Anyone have any advice??
