I am crazy in love with my wife's best friend!!

This has been disturbing me for quite a long time. My wife's best friend is a caring and loving friend who understands and stood by her friend (my wife) during her agonising days. I came to know her after i proposed to my wife and within a Short period, I got married to my wife which her friend became her best maid. As time goes on close to a year, I began having feelings for her to the extend am confused. Despite the fact that I Love my wife so much, I do love her friend too to the extend I feel happy whenever she is around and if she left, I feel as if she has been taken away from me. she is almost my wife in character, understanding, Love and trust. Really I do Love her with all my heart. Now am in love with two women which one happens to be her best friend. Am confuse is it that am lusting after her (though I sometimes fantasied about her) or really am in Love with her ? Despite the fact I can't marry or make advances as in secretly going along with her, I am been overwhelmed by Love for her. (I even thought of keeping them both**Lol**) Is that possible? Loving two women equally? what are the scenarios associated with that? want ur views.
