You never know to whom you will fall in love with. Just take it as a gift. Do not make any analyzes. Just feel it. Do not make any judgments. You do not need to know the result. Just enjoy the process. If one day s/he will be yours, keep and make your love more stronger. But if one day s/he will go, just release her/him free, forgive and forget her/him, s/he is definitely not yours.
