M.Ted,I'm not sure that Suze Rotolo would be a good source for definitive information on this matter. The song dates from 1965. If I recall correctly, her relationship with Dylan ended circa 1963.
Also, while Dylan may not have been nice to Phil Ochs during the '60s, I really don't think you can make the case that it was Dylan who was jealous of Phil. Clearly, it was the reverse. Read Marc Elliot's biography of Phil for some background.
