He's probably treated a thousand times worse at work day in and day out, even on the "weekends" when you're stateside you're almost constantly getting phone calls from your unit and tasks to complete before Monday. I remember just wanting to get food and sleep everyday, my wife and I were young and she was always upset because I didn't even want to have sex most days, I had nothing left physically or emotionally to give but you have to give more and more to the army everyday. The army doesn't care about its soldiers, it replaces you instantly with someone else whether you get out or die. He's probably suck with horrible leadership that is more worried about not getting yelled at by someone higher up. Civilians don't seem to understand that you can't just decide to not listen or just "take 2 weeks off" because you're tired or stressed. If you're getting treated like shit, you just have to take it as a soldier, you can "report" the way you're being treated, and it might even get addressed, but you will pay the price of getting treated worse after that. You're really just stuck. I was in a batallion that treated everyone like trash, when someone tried to stand up for themselves they started finding ways to make his life miserable until he finally shot himself one night. They tried to cover it up, and couldn't. I will never forget the next morning so many people were pissed because battalion knew how people were being treated, but called everyone in early, 430am, for a "fun run", and said there's nothing they could have done different, it was just something that was going to happen no matter what. Then we stayed out at the range all day, they threw a pizza party for dinner and we did night fire exercises until 1am. Leadership went home, and me and some other guys took ammo bank to the bunkers until about 3am. I had to be back at 430am to gear up three next morning. This cycle continued 3 more weeks before so many people started going to the mental hospital that division started asking questions. Deployment... I'll just scratch the surface into the mental, emotional and physical drain that comes with this. Your first deployment you get there and you're scared because stuff keeps getting blown up, incoming alerts all the time, you have to be angry before you go outside the wire because you know you'll just be dead after the IED hits and you turn every feeling of compassion, love or caring off because it hurts too much to be honest with yourself about how you feel about everything and you have to be ready to kill first. By the 3rd month, you don't care if you personally live or die anymore, you survive for your buddies because you don't want to let them down. You stop ducking when things blow up because, "fuck it, if it gets me it gets me". You still train as hard as you can and it's fueled by hate. It consumes you. You don't just turn that off. I've been retired from the army for 5 years now. I'm just starting to learn to be kind, gentle and patient. Small talk makes me sick and even angry if it's someone trying to push an agenda like selling something. Long story short... If you truly love him, help him. He's told everyday that if he gets help he's weak and will just be a shitbag for the rest of his career. You are literally told not to get help. I guarantee it is going to take years for him to even start to act like a human again. He's treating you like he's treated and honestly, he's not going to know he's doing it until he's been out of the military. He's your family. You wouldn't just let your mom, dad, brother or sister suffer alone, you would stick with them. I guarantee, he doesn't know what he's feeling anymore. He just knows he feels wrong inside. As someone who has gone through what he is, he needs love more now than ever, and it's going to be hard on you, so very hard. I promise you, he'll realise what you've done for him in the long run and will pay it back the best way he can and I would be willing to bet, that even now, when it really counts, he would be there for you and your family. He's probably thinking survival and preparation for what if war happens at home, will my family be ready and not are the kids enjoying family game night. It sucks, but that's just the mindset.

My recommendation, ride out the contract and get him into college with the GI Bill. It's going to be hard. Feel free to PM me if you have any questions.
