Im sorry about what you are going through. I have and am still going through a situation like this. The sucky part about it is that it seems to me that no matter whether you tell him now or when he gets back (more so when he gets back) is that he is probably going to try to make your life a living hell. If you tell him now he might start to be nice so you can't leave and might say he's sorry..blah blah blah..but when he gets back he is probably going to threaten to take the kids away and say all kinds of nasty stuff...talking to JAG will not help because they do not deal with divorce matters. I would consult with a lawyer and see what they see because each state is different. I know in d.c. it is a no-fault area meaning you just have to be physically apart from each other for I think it's like 6 months...which in your case if he's deployed, good for you. Well anyway, if you just need someone to talk to email me
