Why I can't run long distances

It has nothing to do with the actual distance. Or my tendency to get diarrhea afterwards. But let me back up.

Last night we had our monthly girls night out. I made dinner for the family and when I finished eating I got in the shower and then left. The dishwasher had been running when I left but it doesn't take more than a couple of hours. When I got home, more than a couple of hours later, the dishes in the dishwasher were clean, but they were the same dishes I left. All of the dinner dishes were piled up next to the sink. I suppose I should be grateful they made it to the sink and weren't left on the table. Bedtime is always before 8 so there was plenty of time for someone to unload and reload the dishes.

Before last Sunday's run I had thought about doing a different route--one that was much hillier--but when I drove down that road I remembered that there is no shoulder at all and every time a car comes from the other direction I always think there's going to be a collision. I mentioned the road to Vader who confirmed that it would be a bad idea. He thought I just wanted a different route (I want to work on more hills) so he suggested I run to the state park 5 minutes from our house. I figured, why not? So I ran to the state park. I knew it would be farther and longer than usual. I figured I'd run to the park, pee, and run back. When I got to mile 2 and I hadn't made it there yet I could have turned around but by that point I needed to stop and pee. So I kept going. It was mile 3 when I made it to the bathroom. It was wicked hot and while most of the way was nice and flat, there were some pretty nice hills too. I didn't want to go from running 4 miles for my long run right up to 6, in the heat, because I was pretty sure I'd be in the bathroom the rest of the day. So I took a few walking breaks. I probably ran 5 out of the 6 miles. I got back home more than an hour after I left. What did I come home to? Can you guess? A sink full of dishes! And Vader on the computer, not even pretending to interact with the children. I had to shower and I had brunch to make so I wound up with an even bigger pile of dishes.

There is nothing more frustrating than coming home from a fun experience and being hit with what your absence meant, especially so visually... It almost feels like a punishment. Like, sure you can go out and run for an hour and I'll keep the house from burning down and the kids from escaping, but you'll still have to do all the drudge work only now you'll have much less time to do it. I'm sure that this is not intentional on his part, but this is the message that I get, the feeling that I get, and all of the positive feelings I have from running or being at girls night fly out the window.

How can I train for a 10K so that I can actually run all 6 miles at a decent pace? How could I train for a half-marathon?? It's not enough to have verbal support, it's not enough to say "yeah, go out for a run." I need someone to pick up the slack in my absence and not just watch TV with the kids.
