Familyman2, whenever you go to court on anything, you need to keep the other side guessing. The other posters gave you very good advice not to post what your next steps are. Always consult with your attorney.
Another point to ponder: You can present what you want the scenario to be, but keep in mind that your stbx wife will have her own lawyer who will advise her on her rights. She sounds like she will make it very difficult. I just don't want you to be disappointed when you are not able to get everything in your perfect scenario. Keep in mind that if you don't get everything you want, you need to do your best to make whatever outcome work for the best interest of the children.
