You mentioned that you ONLY have a couple hours at night... "Not like I'm around for hours with no kids", you said... well, actually it IS like you are aroudn for hours with no kids...
If you are like me (or say jbnati), you've got enough energy to stay awake until midnight (and then some) and still get up on time to get to work in the morning.
So DO that. GET OUT for a couple hours. Even if it means taking your laptop and going to the local internet cafe and posting here.
As far as filing D? If YOU file... you can always quit the claim at a later date.
