When Brent was gone for 1 yr over to Korea it was hard. Alex and Kyle were 2 yrs and 2 1/2 mos when he left. I usually let most things go, small things...not that I really wanted to but Kyle was really sick for his first year of life I had to give him breathing treatments every 2 hrs for 8 mos. even at night, so not much got done, not to mention I dind';t get much sleep either I had to set alarm to wake up every 2 hrs.
Anyway, since Alex was a very finicky eater and I wasn't much into cooking for just me we would go out at least once a week or eat with a friend who's husband was also gone. For the other times he was gone, shower at night, dishes at night, etc. To brighten up my week I'd goo to the library and "rent" movies that he hated but I wanted to see, popped popcorn or get a pizza ( 2-3 meals from that) anything that I normally couldn't do I did when he was gone (we only had 1 car at the time, so I rarely got out)...I also went home a few times like you do. All in all, concentrate on the kids till Fri morning then run around like the mad hare claning up before he came home....otherwise it'd look the same in 1 hr....who's there but you to notic?
