As professional Matchmakers, we at Executive Search Dating know that selecting someone's perfect match is part science and part art.  Furthermore, every person has a different selection of criteria that are particularly important for them.  Having said that, here are 3 'classic' signs that you have met someone special:

1. Physical chemistry: do you find the person physically attractive? It is not uncommon to have chemistry with someone who isn't 'your type'.
2. Conversational connection: does conversation flow naturally or feel forced? If laughter comes easily for both parties its a good sign.
3. Family views: do you both have similar family views; both about having a family and your views towards your own family?
