It is more likely for someone not to approach another person because of a fear of being shot down.  However, statistics show taking that leap will yield better results than the weight of conflict you hold in your head about being shot down.

We are often harder on ourselves about how others view us than the actual perceptions they have of us.  If you get shot down, don’t take it too hard.

It likely has nothing to do with you, but the person you approached may be in a relationship, simply not interested in dating, or a number of other items that have nothing to do with you.
