What's worse? Dad having visitation, or Dad having full custody?
Even if there was only a slim chance that you'd be found if you ran, the fact that you are willing to risk even a slim chance that your precious child could end up in the custody of such a horrible person makes even the suggestion of running completely idiotic.
You're not thinking about what's best for your child.
If you try to think like an adult, you might be inspired to act like one.
It's a very serious thing to do, I know, thats why I am here asking about the possible consequences.
