I want to have primary custody of my kids and move them across the country from their father and his family so I can start my dream job.
Why would you want to move away?
For a better life for them.
It is good to want a better life for your children but separating them from their other parent is wrong. It could be better to spend more time with a parent since that can affect a kid more.
Shut up, who are you to tell me what to do with them.
Sounds like you're just trying to spite the other parent. Would you like it if he did the same to you?
