I am try to remove the spout from the tub. I can to it in both directions but it will not screw off the pipe. Help

Your spout is most likely installed on a copper stub-out - not on a threaded nipple. There is a small set screw on the bottom set inside a small hole on the body of the spout. Locate the screw, loosen it with a bit with allen wrench and the spout will slide out. No twisting necessary...
