Why would there be any jealousy in a healthy relationship? If it's healthy relationship then there should be complete trust between the two partners, if there's complete trust then there should be no jealousy whatsoever. Now there would be protectiveness, fearing for their wellbeing, and a partner in a good relationship would ask the other questions about where they're going, who with, etc. not because of jealousy but because of fear for their well-being and protectiveness. So I say there should be no jealousy in a healthy relationship. If u know that the other person loves u dearly and wouldn't do anything to hurt u and u trust them then there should be no problems at all, and if there was a problem then u can talk out cause at the end of the day u love eachother and that's what counts.
