Fulfillment is a feeling or emotion that is very close to satisfaction and contentment combined. If you are fulfilled in your career then you are happy where you are, and you do not want to do anything else. Fulfillment in marriage or a romantic relationship means that you are not looking elsewhere, and even if the opportunity to be unfaithful does come up you would refuse.
