Child support and moving

Hello everyone so my baby daddy calls me bitter & miserable cause I have him on childsupport. He has never done anything for him....

He only gets him a few hours of the day on every Sat....

He use to get him alot more but since hes been with a new girl he doesn't.

So I wanted to move to another state. We dont have no visitation arrangements whatsoever...

When I move the courts will lower the childsupport correct?

And they will also give him visitation arrangement correct like every break and so on ...?

I know once I move hes gonna try to take me to court ONLY because he wants to be taking off of childsupport. I got this in messages him saying I'll let ungo only if you take me off. And I asked him how he could be so selfish when you barely get him now and he said cause he can just like you can have me on childsupport. I use to try to force this man to get his son.

One time I got off of work late and I told him I'll be two hours late and he told me I owe him $30 for taking his time from his son. LIKE WHAAAA. His dad lives 10 mins down the road literally and i told him hes ready for you and he told he didnt want him and he'll get in the morning.

He wants me to take him of so he can live his life with his new girl...

He never calls or text about him just about me taking him off childsupport and him threatening me to go down to the courts??

What can he do?
