Husband's stress is causing him to act differently

My husband has been working extremely hard lately and is almost never home. He works 10-14 hour shifts at times and I know as much because I've seen his work history/time punches etc. But ever since he has started this position he will stop at nothing to get promoted. Everytime another employee calls off he is the first to pick up slack. He is acting very distant even though he is still nice, he doesnt open up about stuff and is only home to sleep ( which is understandable when all he does is work) so I'm not against that of course! . Sometimes he takes hours even after coming home to unwind and barely says a thing to me until right before bed. His stress is adding to mine and idk how to fix it for either of us. We barely have sex unless its quick and I do all the work, and we dont talk much at all in the week. Even on his off days he will uber or pick up shifts at another job. I've gotten very depressed and feel like I'm falling apart as a wife and mother to be.

Any advice for either of us? Thanks xo
