Need some advice..My husband is deployed?

My husband has been in the Army for 5 years. He didn't know that he would hate it but he does. He hates it so much he was depressed. I didn't know he was this way when I married him. I didn't know the military affected his life so bad. We alot of problems, arguing about difference's we had. We never cheated and we don't have money problems. Well they stop lossed him which means he was suppose to get out this month, but they sent him to Kuwait for 15 more months. He is worse then he was when he was herer. He says mean things when I try to talk to him about money or our daughter. Sometimes I am just here alone and I think about divorce. I love my husband but..... me being alone here is making me think way too much. I know I would be fine if he was home. Anyone know how i can deal? And I am not talking about being alone.....and then cheating..I would never cheat .
