Oh yeah... I'm already pushing the separation agreement. I'll let that settle and then see how things are going.
Good...you're looking out for you and your girls. I don't know what the law is like in Kentucky. In California, once you have a separation agreement in place, all you have to do is amend it and wait 6 months for final dissolution if that is what you want. That will give you a lot more control over your own destiny.
One question I have: What is the custody arrangement that you have, or hope to have? The reason I ask is that you seem to be the stable, consistent parent in your situation. I'm not suggesting that you try to exclude your W at all, but I think 50/50 (at least) would be appropriate.
