Lucky for you, the courts in Okla have been moving to shared parenting for the last few years. It isn't as hard as it used to be to get shared custody. I can tell you this, one stupid move on your part will make it almost impossible to achieve this. I would suggest you eliminate any more threads concerning this issue, especially if she knows you frequent this site..
Agreed, I got full custody of my very young children,(2yr.old and 3yr.old) in 95 when it was a lot tougher. But even if it's changing you need to be careful and plan well.
