I'm going to ghost my children
Why would you want to ghost your children?
I am not ready to be a father yet.
I understand what you're saying, but it is absolutely wrong to abandon your children like that. You are their parent and you should take care of them and spend time with them and remain engaged in their life. If you don't, it reflects terribly on your character and you kids might not want you to be part of their lives after a while.
It's fine. If my children hate me, I hate them too.
You need to take care of your kids, abandoning them is something that could harm them as an adult. What do you think they will do if they feel you rejected then they could grow up angry and become criminals or something.
