You have to start on the right foot with your relationship. But speaking about relationships, with my first marriage my ex was very jealous and I never gave her a reason for her to act that way. Relationships are a two way street and speaking from a senior citizen point of view you well want some space when you get married. Having friends is a good thing, my second marriage has worked out for that reason. I play golf twice a week and I go to a lot of car shows and car swap meets without her with no issues. I always get the last word in (Yes honey).
Its all about mutual trust.
