"Half the month" -
1. Don't commute! Live in base. If you can move to do this, do it.
2. Bid reserve. If you live in base, this could be advantageous to you. This month has been pretty busy on reserve for me and I'll only be "away from home" eight nights sleeping in a hotel bed (12 days of work). That is still 19 days at home. I was full time military before this job and I see my kids more now than I did before. I am not talking about deployments either; just normal, every day, home station Ops working a desk for 9 hrs a day with a 45 min commute on either side. I was up and out of the house before anyone else got up and I wouldn't get home until 2-1/2 hrs after my kids got home from school. Now, when I am home, I can walk them to/from the bus stop.
On the other side of things, time away from your spouse can provide a healthier relationship. Works for me.
