I never get to visit my child(ren) Can I stop paying child support?

The answer to this is simply, "No." Visitation and child support are two separate and distinct issues. The custodial parent has a duty to allow the non-custodial parent visitation with the child(ren), and the non-custodial parent has the duty to pay child support. If there is interference in your visitation, you must seek to have the visitation enforced. There are legal repercussions if you stop paying child support just as there are legal repercussions for interfering with visitations.
