work 24/7, not single but no support

If possible you might want to get him to a therapist. I know from personal experience, things go sour if one person is burdening their partner with all their emotional problems and not offering support for the other. I think it would help you guys out a lot. He would have someone else to talk with about his internal problems and you could focus on having a fun and healthy relationship. I don't think it's good for either of you if you're taking on your own stress and his combined. Go out and have a few beers with some girlfriends, blow off some steam.
