Incidentally, I have had a similar sounding experience, yet as a male. So I'm speaking from his perspective I guess. I worked with at risk youth during the time that I was with my last girlfriend. The work was mentally exhausting and I was definitely depressed.

I am a little younger and don't have kids, but the effects of my depression were debilitating when I was with her. She wanted to have sex with me every day (several times a day). I couldn't handle it and told her that "I needed time to recharge." She gave me a lot of problems about it but did listen and I was able to do it every other day.

When the male mind gets overwhelmed with stress we shut down. Which is probably why he played battlefield for so long. I am guilty of that as well...maybe not for 4 hours...but I often wanted to escape into video games or away.

The best advice I can give is give him the ability to relax and recharge. Work slowly on him, love him, and know that his mind isn't all there at this moment. He loves you too, he's just a little lost right now. It will come back. He is your husband, he helps those in need every day, and you have kids with him. Sounds like a pretty awesome person .

Also take care of yourself in healthy ways. You deserve to do what you want to do as well. You are awesome for taking care of so many things when he is doing other things. You are making sure that things don't completely come crashing down and deserve to be acknowledged for that.
