Visualise the person you love.  The person you wish to know if they feel the same for you.

Light a White Candle, and Say:
 

 “Aphrodite,
 I believe there are feelings between .....(person).... and I,
 Please help to nurture these feelings, and keep them strong
 So that we may be together, and be happy together.
 If these feelings no longer/do not exist, 
or if it is not the will of the Universe for us to be together,
May I find out now, gently but clearly.
With Harm to none, So Mote it Be!”

Farewell Aphrodite and close the Circle as you usually would.

Bury the candle in the ground for a week. Look for signs that will answer your question.  If your answer hasn't been given, dig up the candle and repeat the spell.  

If you have received your answer, Dig up and Light the candle again and thank the Goddess by sprinkling some flowers over a stream/river/ocean (or failing this, a bowl of water you pour onto the garden), and thank her for answering you.

You may either re-bury the candle, keep it, or whatever you feel is right to do with it.
