What NT people are trying to say is that if a relationship occurs, it should be natural and you both should feel at ease. It should not feel force and that is why they tell you not to worry. You worry because you want guidance on your actions. The best way to get support if you don't have a close set of friends is to get a counselor, ask for advice on a forum, and/or look for an expensive life coach who would be more available than once a week or at a moment's notice if you need it. Most life coaches are not certified in psychology, but they can generally be more available than 1 hr a week or at an instant that a general psychologist cannot be.
