My boyfriend and I are in the same place as you and your husband are, and we will be for the next 3-5years.
We both work full time and I go to school full time, and he'll be starting to go to school full time soon. We're really committed to each other, but it does make things harder when you barely ever see each other. Thats why I don't want to get married until we're almost done with school. Its just to much pressure.
I don't know what I would say in your situation. If the money he gets from his job isn't that vital, I'd just tell him that no "foot in the door" position is worth harming your relationship over. Good luck.
