The one thing to remember in any custody battle is that it all revolves around the BEST INTERESTS OF THE CHILD...
The best thing you can do is to do everything in your power to remain the calm, stable, manageable one.
Also, you mentioned you were in the military. Are you active duty? Really doesn't matter, but you have lawyers available to you for advise on this... There are lawyers there that are versed in family law and they have the books available for all 50 states.
Talk to one about this, letting him/her know that you're doing this Pro Se. Also, maybe they would be willing to look at all of your filings to make sure they are appropriate to form.
Last, get a membership to
http://www.versuslaw.com. Socrateaser recommened it to me several months ago and it has been a God send... Look up case law that is related to your case. It would help give you ideas as to how to approach yours. The membership is $11.95 a month and it's well worth it.
I used versuslaw to find case law so we could sue my hubby's ex wife for all the stuff she put us thru over the years. We just won a default judgment for just over $950,000.00.
I completely credit this site, Soc and versuslaw for giving me the courage to do this.
And do check out the sites Brent gave you. Not only is he a tremendous help and a great asset to this site, the articles he's recommending are some of the best advice you'll get.
Lastly, tho she might not be one now, the family court is very good at creating narcissists. They have the uncanny ability to allow these women to do whatever they want, whenever they want, to whomever they want, with little or no repercussions. There is an article online about dealing with the narcissist in court. There's a link to it from the articles page.
http://www.deltabravo.net/custody/narcissist.htm Extremely informative article and it has helped me win more than one verbal battle with my hubby's ex.
Good luck to you. You offer more stability than the mom, she bounces around, you are in a stable job, in a stable environment.
Also, when they get around to asking about day care arrangements, when the home study is done, thru the Family support center on base, they maintain a listing of certified day care providers that are certified thru the base. They are all wonderful and my 9 year old has had more than one and loved them all. When my hubby retired from the USAF, his day care provider cried, she was going to miss Eli so much.
