Whether your son wants to see you or not he deserves support (i.e. food, clothes, shelter, etc) from both parents. You won't get the court to eliminate the support just because your kid doesn’t want to see you. Support is NOT paying for your kid to see you.
Teens being what they are, his desire not to see you may have as much to do with you being more strict than his mother than any parental alienation. Teens, after all, push the boundaries and tend to think they ought to be able to do whatever they want. So they run into conflicts with parents who set rules and limits on what they can do.
