FLTC,
Have you started that savings account for YOU and your future???
(I know I promised I wouldn't nag you about that, but you just need some friendly nagging now and then!!!)

Can you foresee getting a house or apt near where the family house is now and the kids can walk back and forth easily? Can you foresee selling that house and you end up with 2 smaller places? Maybe you can decide to live near each other so the kids can be in the same school district no matter who they are with. Will you even be stationed in the same place when you return from Iraq? Who's to say that the kids won't want to be at your new place more than at their current location? Mom's don't always get custody!!!! You can hire a lawyer and listen to him/her (Do as I say, not as I do!)
