Life is strange. Sometimes the best matches for us, even our ideal match, pass us by because we don't connect with them. We later come to regret doing it. Perhaps the explanation is that you are not in the proper setting at the right time, the other person is too bashful to approach, or the other person is reluctant to take a chance because they are terrified of failing. This also holds true for folks who are very attractive or have a high level of notoriety and do not want to take a chance.
